Efficient Synthesis of Diphenyl Carbonate from CO₂, Phenol, and Carbon Tetrachloride under Mild Conditions was written by Wang, Songlin;Jiang, Nan;Peng, Jiali;Yang, Peng;Cui, Chengxing;Niu, Hongying;Zhang, Qiying;Wang, Jianji. And the article was included in ACS Sustainable Chemistry & Engineering in 2022.Synthetic Route of C13H10O3 The following contents are mentioned in the article:

Herein, an efficient catalytic system for the direct synthesis of DPC from CO₂, phenol, and carbon tetrachloride was developed by using a ZnCl₂/copper triflate (Cu(OTf)₂) composite catalyst. For the first time, high yield and high selectivity were achieved for DPC synthesis under mild conditions, even at atm. pressure. Carefully designed control experiments and DFT studies indicated that the synergistic activation of Cu(OTf)₂ and its anion complex with ZnCl₂ for phenol and CO₂ led to a remarkably improved catalytic activity through a Lewis acid-assisted catalysis. This study not only provides a new strategy for efficient preparation of DPC but also offers an effective pathway for better CO₂ utilization. This study involved multiple reactions and reactants, such as Diphenyl carbonate (cas: 102-09-0Synthetic Route of C13H10O3).

Diphenyl carbonate (cas: 102-09-0) belongs to esters. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits, including apples, durians, pears, bananas, pineapples, and strawberries. Many esters have the potential for conformational isomerism, but they tend to adopt an s-cis (or Z) conformation rather than the s-trans (or E) alternative, due to a combination of hyperconjugation and dipole minimization effects. The preference for the Z conformation is influenced by the nature of the substituents and solvent, if present. Lactones with small rings are restricted to the s-trans (i.e. E) conformation due to their cyclic structure.Synthetic Route of C13H10O3

New Synthetic Approach to Polyfluorinated Carbonates was written by Semenova, A. M.;Ezhikova, M. A.;Kodess, M. I.;Zapevalov, A. Ya.;Pestov, A. V.. And the article was included in Russian Journal of Organic Chemistry in 2020.HPLC of Formula: 102-09-0 The following contents are mentioned in the article:

Transesterification of com. titanium(IV) alkoxides with 2,2,3,3-tetrafluoropropan-1-ol, followed by in situ transesterification of mixed titanium(IV) alkoxides thus formed with di-Ph carbonate, afforded alkyl 2,2,3,3-tetrafluoropropyl carbonates I [R = Et, i-Pr, n-Bu; R¹ = OCH₂CF₂CF₂H] and bis(2,2,3,3-tetrafluoropropyl)carbonates I [R = R¹ = Et, i-Pr, n-Bu] in up to 60% yield. The degree of transesterification decreased in the series (i-PrO)₄Ti > (EtO)₄Ti > (BuO)₄Ti and did not exceed 68%. The selectivity for alkyl 2,2,3,3-tetrafluoropropyl carbonates and bis(2,2,3,3-tetrafluoropropyl)carbonate was found to change depending on the composition of mixed titanium(IV) alkoxide formed in situ. This study involved multiple reactions and reactants, such as Diphenyl carbonate (cas: 102-09-0HPLC of Formula: 102-09-0).

Diphenyl carbonate (cas: 102-09-0) belongs to esters. Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones. Cyclic esters are called lactones, regardless of whether they are derived from an organic or inorganic acid. One example of an organic lactone is γ-valerolactone.HPLC of Formula: 102-09-0

Organocatalytic Synthesis of Substituted Vinylene Carbonates was written by Onida, Killian;Haddleton, Alice J.;Norsic, Sebastien;Boisson, Christophe;D’Agosto, Franck;Duguet, Nicolas. And the article was included in Advanced Synthesis & Catalysis in 2021.Electric Literature of C13H10O3 The following contents are mentioned in the article:

The organocatalytic synthesis of substituted vinylene carbonates from benzoins and acyloins was studied using di-Ph carbonate as a carbonyl source. A range of N-Heterocyclic Carbene (NHC) precursors were screened and it was found that imidazolium salts were the most active for this transformation. The reaction occurs at 90°C under solvent-free conditions. A wide range of substituted vinylene carbonates (sym. and unsym., aromatic or aliphatic), including some derived from natural products, were prepared with 20-99% isolated yields (24 examples). The reaction was also developed using thermomorphic polyethylene-supported organocatalysts as recoverable and recyclable species. The use of such species facilitates the workup and allows the synthesis of vinylene carbonates on the preparative scale (>30 g after 5 runs). This study involved multiple reactions and reactants, such as Diphenyl carbonate (cas: 102-09-0Electric Literature of C13H10O3).

Diphenyl carbonate (cas: 102-09-0) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Polyesters are important plastics, with monomers linked by ester moieties. Because of their lack of hydrogen-bond-donating ability, esters do not self-associate. Consequently, esters are more volatile than carboxylic acids of similar molecular weight.Electric Literature of C13H10O3

And the article was included in ChemSusChem in 2021.Product Details of 102-09-0 The following contents are mentioned in the article:

Chem. upcycling of poly(bisphenol A carbonate) (PC) was achieved in this study with hydroxamic acid nucleophiles, giving rise to synthetically valuable 1,4,2-dioxazol-5-ones and bisphenol A. Using 1,5,7-triazabicyclo[4.4.0]-dec-5-ene (TBD), non-green carbodiimidazole or phosgene carbonylation agents used in conventional dioxazolone synthesis were successfully replaced with PC, and environmentally harmful bisphenol A was simultaneously recovered. Assorted hydroxamic acids exhibited good-to-excellent efficiencies and green chem. features, promising broad synthetic application scope. In addition, a green aryl amide synthesis process was developed, involving one-pot depolymerization from polycarbonate to dioxazolone followed by rhodium-catalyzed C-H amidation, including gram-scale examples with used compact disks.

Redox-Neutral TEMPO Catalysis: Direct Radical (Hetero)Aryl C-H Di- and Trifluoromethoxylation was written by Lee, Johnny W.;Lim, Sanghyun;Maienshein, Daniel N.;Liu, Peng;Ngai, Ming-Yu. And the article was included in Angewandte Chemie, International Edition in 2020.Recommanded Product: 102-09-0 The following contents are mentioned in the article:

Applications of TEMPO· catalysis for the development of redox-neutral transformations are rare. Reported here is the first TEMPO·-catalyzed, redox-neutral C-H di- and trifluoromethoxylation of (hetero)arenes. The reaction exhibits a broad substrate scope, has high functional-group tolerance, and can be employed for the late-stage functionalization of complex druglike mols. Kinetic measurements, isolation and resubjection of catalytic intermediates, UV/visible studies, and DFT calculations support the proposed oxidative TEMPO·/TEMPO⁺ redox catalytic cycle. Mechanistic studies also suggest that Li₂CO₃ plays an important role in preventing catalyst deactivation. These findings will provide new insights into the design and development of novel reactions through redox-neutral TEMPO· catalysis.

Recycling system that converts plastic into fertilizer was written by Aoki, Daisuke;Otsuka, Hideyuki. And the article was included in Konbatekku in 2022.Quality Control of Diphenyl carbonate The following contents are mentioned in the article:

More than 70% of the polymer materials (plastics) that are indispensable for daily life are discarded. In order to recycle plastics, it is necessary to selectively collect only plastics from all waste products and carry out a recycling process according to the type of plastics, but the problem to be solved in any case is is left. Focusing on the recycling process related to this article, two typical recycling processes (material recycling and chem. recycling) can be briefly mentioned by collecting, processing and reusing used plastics. In “Material Recycling”, the color is suitable due to foreign matter contamination and the quality is deteriorated due to the deterioration of the mol. chamber that occurs in the recycling process. In this article, the author devices a method to degrade the polycarbonates to produce fertilizers for plants from plastic wastes. This study involved multiple reactions and reactants, such as Diphenyl carbonate (cas: 102-09-0Quality Control of Diphenyl carbonate).

A New Class of Oxyimides: Oxyimide Ethers and Their Use as Flame Retardants was written by Spiess, Bianca;Metzsch-Zilligen, Elke;Pfaendner, Rudolf. And the article was included in Macromolecular Materials and Engineering in 2021.Name: Diphenyl carbonate The following contents are mentioned in the article:

Oxyimides have gained wide interest in different applications because of radical generating properties, such as flame retardants in various polymers. As polyamide-6 (PA6) is highly flammable and shows burning dripping during incineration the mentioned issues have to be overcome by the use of a flame retardant. All previously developed oxyimides already show these properties, but this is based on the ester structure with the consequence of transesterification/transamidation in polyesters/polyamides. In this work, a new class of oxyimides based on ether bonds is synthesized. Oxyimide ethers do not degrade PA6, only sometimes slightly increase MVR, and show excellent flame retardancy in PA6. Depending on the structure, UL 94 V-0 can be reached with very low loadings. This makes oxyimide ethers an alternative to commonly used flame retardants for PA6. This study involved multiple reactions and reactants, such as Diphenyl carbonate (cas: 102-09-0Name: Diphenyl carbonate).

Diphenyl carbonate (cas: 102-09-0) belongs to esters. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits. Esters are more polar than ethers but less polar than alcohols. They participate in hydrogen bonds as hydrogen-bond acceptors, but cannot act as hydrogen-bond donors, unlike their parent alcohols. This ability to participate in hydrogen bonding confers some water-solubility.Name: Diphenyl carbonate

Preparation of Azido Polycarbonates via Bulk Polymerization of Halogenated Diols was written by St-Charles, Jean-Christophe;Dubois, Charles. And the article was included in Propellants, Explosives, Pyrotechnics in 2020.Reference of 102-09-0 The following contents are mentioned in the article:

Azido polymers find use as energetic binders in a variety of composite explosive and propellant applications, but few azido polyesters have previously been reported: a method is introduced for the preparation of two azido polycarbonates, poly(2,2′-bisazidomethyl-1,3-Pr carbonate) and poly(3-azido-1,2-Pr carbonate), possible binder candidates for energetics applications. The preparation method for these polymers involves a two-step synthesis starting from the bulk polymerization of the com. sourced diols with di-Ph carbonate in the presence of lanthanum (III) acetylacetonate as a neutral catalyst, and subsequent azidation in cyclohexanone. The phys. and thermal characteristics of each are reported, indicating properties similar to other azido-polymers. The thermal and mech. properties of cured azido polyester resin mixtures are the subject of ongoing research. This study involved multiple reactions and reactants, such as Diphenyl carbonate (cas: 102-09-0Reference of 102-09-0).

Targeting KRAS Mutant Cancers via Combination Treatment: Discovery of a 5-Fluoro-4-(3H)-quinazolinone Aryl Urea pan-RAF Kinase Inhibitor was written by Huestis, Malcolm P.;Dela Cruz, Darlene;DiPasquale, Antonio G.;Durk, Matthew R.;Eigenbrot, Charles;Gibbons, Paul;Gobbi, Alberto;Hunsaker, Thomas L.;La, Hank;Leung, Dennis H.;Liu, Wendy;Malek, Shiva;Merchant, Mark;Moffat, John G.;Muli, Christine S.;Orr, Christine J.;Parr, Brendan T.;Shanahan, Frances;Sneeringer, Christopher J.;Wang, Weiru;Yen, Ivana;Yin, Jianping;Siu, Michael;Rudolph, Joachim. And the article was included in Journal of Medicinal Chemistry in 2021.Application In Synthesis of Diphenyl carbonate The following contents are mentioned in the article:

Optimization of a series of aryl urea RAF inhibitors led to the identification of type II pan-RAF inhibitor GNE-0749 (7)(I), which features a fluoroquinazolinone hinge-binding motif. By minimizing reliance on common polar hinge contacts, this hinge binder allows for a greater contribution of RAF-specific residue interactions, resulting in exquisite kinase selectivity. Strategic substitution of fluorine at the C5 position efficiently masked the adjacent polar NH functionality and increased solubility by impeding a solid-state conformation associated with stronger crystal packing of the mol. The resulting improvements in permeability and solubility enabled oral dosing of 7. In vivo evaluation of 7 in combination with the MEK inhibitor cobimetinib demonstrated synergistic pathway inhibition and significant tumor growth inhibition in a KRAS mutant xenograft mouse model. This study involved multiple reactions and reactants, such as Diphenyl carbonate (cas: 102-09-0Application In Synthesis of Diphenyl carbonate).

Investigation of masked N-acyl-N-isocyanates: Support for oxadiazolones as blocked N-isocyanate precursors was written by Gagne-Monfette, William;Vincent-Rocan, Jean-Francois;Lutes, Owen C.;O’Keefe, Genevieve F.;Jeanneret, Alexandria D. M.;Blanger, Claire;Ivanovich, Ryan A.;Beauchemin, Andre M.. And the article was included in Chemistry – A European Journal in 2021.Category: esters-buliding-blocks The following contents are mentioned in the article:

In contrast to carbon-substituted isocyanates that are common building blocks, N-substituted isocyanates remain underdeveloped and reports on their N-acyl derivatives (i. e. amido-isocyanates) are exceedingly rare. Herein, amido-isocyanates were investigated in the context of syntheses of aza-tripeptide and hydantoins subunits starting from simple bench-stable precursors. A key finding is that the amido-isocyanate formed in situ cyclized to yield an oxadiazolone, and that under suitable reaction conditions this heterocycle is a traceless blocked (masked) N-isocyanate. Using organic bases as catalysts and upon heating, oxadiazolone formation is observed, and various nucleophiles to provide the desired aza-dipeptides or hydantoins in moderate to high yields. Further support for an amido-isocyanate intermediate was obtained using carboxylic acids as nucleophiles, affording N-acylhydrazide products. This study involved multiple reactions and reactants, such as Diphenyl carbonate (cas: 102-09-0Category: esters-buliding-blocks).
