And the article was included in Organic Letters in 2021.Quality Control of Diphenyl carbonate The following contents are mentioned in the article:

To develop a new nucleoside analog applicable to oligonucleotide therapeutics, we designed a 4′-thio analog of an LNA/BNA monomer. Synthesis of 4′-hydroxymethyl-4′-thioribonucleoside was achieved by a tandem ring-contraction-aldol reaction of a 5-thiopyranose derivative and the subsequent Pummerer-type thioglycosylation reaction of the corresponding sulfoxide. Treatment of 4′-hydroxymethyl-4′-thiopyrimidine nucleosides with di-Ph carbonate in the presence of catalytic NaHCO₃ gave the desired 4′-thioLNA/BNA monomers, which were introduced into oligonucleotides. This study involved multiple reactions and reactants, such as Diphenyl carbonate (cas: 102-09-0Quality Control of Diphenyl carbonate).

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.Quality Control of Diphenyl carbonate

Photo-on-demand Phosgenation Reactions with Chloroform Triggered by Cl₂ upon Irradiation with Visible Light: Syntheses of Chloroformates, Carbonate Esters, and Isocyanates was written by Suzuki, Yuto;Liang, Fengying;Okazoe, Takashi;Okamoto, Hidekazu;Takeuchi, Yu;Tsuda, Akihiko. And the article was included in Chemistry Letters in 2022.COA of Formula: C13H10O3 The following contents are mentioned in the article:

Chloroform (CHCl₃) upon bubbling with O₂ containing ∼2% Cl₂ underwent oxidative photochem. conversion to phosgene (COCl₂) when exposed to a white LED light. Cl₂ may serve as a visible light-responsive radical initiator in the radical chain reactions of CHCl₃ and O₂. This photochem. reaction allowed both in situ and stepwise one-pot phosgenation reactions, which are simple and safe methods, without expensive apparatus It can be applied to a variety of conventional organic syntheses using phosgene and phosgene oligomers. This study involved multiple reactions and reactants, such as Diphenyl carbonate (cas: 102-09-0COA of Formula: 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. Esters contain a carbonyl center, which gives rise to 120° C–C–O and O–C–O angles. Unlike amides, esters are structurally flexible functional groups because rotation about the C–O–C bonds has a low barrier. Their flexibility and low polarity is manifested in their physical properties; they tend to be less rigid (lower melting point) and more volatile (lower boiling point) than the corresponding amides.

Manganese-Catalyzed Hydroborations with Broad Scope was written by Ghosh, Pradip;Jacobi von Wangelin, Axel. And the article was included in Angewandte Chemie, International Edition in 2021.Application of 102-09-0 The following contents are mentioned in the article:

Reductive transformations of easily available oxidized matter are at the heart of synthetic manipulation and chem. valorization. The applications of catalytic hydrofunctionalization benefit from the use of liquid reducing agents and operationally facile setups. Metal-catalyzed hydroborations provide a highly prolific platform for reductive valorizations of stable C:X electrophiles. Here, the authors report an especially facile, broad-scope reduction of various functions including carbonyls, carboxylates, pyridines, carbodiimides, and carbonates under very mild conditions with the inexpensive pre-catalyst Mn(hmds)₂. The reaction could be successfully applied to depolymerizations This study involved multiple reactions and reactants, such as Diphenyl carbonate (cas: 102-09-0Application of 102-09-0).

Diphenyl carbonate (cas: 102-09-0) belongs to esters. Esters are also usually derived from carboxylic acids. It may also be obtained by reaction of acid anhydride or acid halides with alcohols or by the reaction of salts of carboxylic acids with alkyl halides. 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.Application of 102-09-0
