The Pd-catalyzed alkoxycarbonylation of alkenes using water as a promoter has been scarcely reported before. Herein, water instead of Bronsted/Lewis acid was found to effectively improve the catalytic performance of Pd (MeCN)(2)Cl-2-Xantphos system for alkoxycarbonylation of alkenes. Under the optimal conditions, the best yield of 97% was obtained for the target products (methyl 3-phenylpropanoate and methyl 2-phenylpropanoate) with L/B of 4.3 and TON of 192. With the involvement of water, Pd(MeCN)(2)Cl-2-Xantphos system also exhibited the moderate to good generality to alkoxycarbonylation of different kinds of alkenes with alcohols. The in situ high pressure FT-IR analysis verified that water played an important role in promoting formation and stability of Pd-H active species which was responsible for the efficient alkoxycarbonylation of alkenes. In addition, the ligand effect of Xantphos on this reaction was discussed.

Herein we report the photo- and electrochemical characterization of pyrimidopteridine N-oxide-based heterocycles. The potential of their application as organic photoredox catalysts is showcased in the photomediated contra-thermodynamic E -> Z isomerization of cinnamic acid derivatives and oxidative cyclization of 2-phenyl benzoic acid to benzocoumarin using molecular oxygen as a mild oxidant. Furthermore, unprecedented intermolecular non-covalent n-pi-hole interactions in solid state are discussed based on crystallographic and theoretical data.

A biocompatible hybrid system composed of graphene oxide (GO), chitosan (CS) and ionic liquid decorated cyclodextrin nanosponge (CDNS-IL) is synthesized and applied for the immobilization of Pd and Fe3O4 nanoparticles to furnish a magnetic catalyst, Fe3O4/Pd@Hybrid. The justification for designing this hybrid system was benefiting from the capability of CDNS for formation of inclusion complex with substrates and acting as phase transfer agent. Moreover, IL itself could exert catalytic activity and improve anchoring Pd, while magnetic nano particles could render the catalyst easily separable. Moreover, the functional groups on CS could contribute to Pd anchoring. The catalytic activity of Fe3O4/Pd@Hybrid for promoting hydrogenation of nitro arenes and two coupling reactions in aqueous media was investigated. The results established that the catalyst could efficiently promote all the reactions under mild reaction condition. The investigation of the catalyst recyclability confirmed that the catalyst could be recycled for three reaction runs. (C) 2018 Elsevier B.V. All rights reserved.

The American Matsutake, Tricholoma magnivelare (Peck) Redhead, is an edible wild mushroom with a distinctive aroma described as mushroom and spice with subtle floral and citrus nuances. In this study, a total of 36 odorants were identified from T. magnivelare using solvent-assisted flavor evaporation and aroma extract dilution analysis. Stable isotope dilution assays were performed to quantitate 14 odorants with flavor dilution factors >= 64. Odorants with high odor activity values (OAVs) included 1-octen-3-one (OAV 2125), linalool (OAV 650), (2E,4E)-nona-2,4-dienal (OAV 304), and 1-octen-3-ol (OAV 206). An odor simulation model matched the odor profile of the fresh mushroom. Omission studies showed that linalool, hexanal, (2E,4E)-nona2,4-dienal, methyl (E)-3-phenylprop-2-enoate, and 1-octen-3-one or 1-octen-3-ol were essential to the aroma of T. magnivelare. Chiral chromatography showed that a-pinene was a scalemic mixture of 34% (R)-(+) to 66% (S)-(-), while 1-octen-3-ol was present as 95% (R)-(-) to 5% (S)-(+), and linalool was 96% (R)-(-) to 4% (S)-(+). These results establish the base for future investigations into the aroma chemistry of other members of the genus Tricholoma.

The Name is Methyl 3-phenyl-2-propenoate. Through research, I have a further understanding and discovery of 103-26-4.

In this study, the surface of magnetic MCM-41 nanoparticles (MCM-41/Fe3O4) was modified by 3-aminopropyltriethoxysilane (APTES) and further, 1-methyl imidazole was anchored on their surface using cyanuric chloride as a linker. Then, Pd2+ ions were immobilized on the surface of the modified MCM-41/Fe3O4 (Pd-imi-CC@MCM-41/Fe3O4), and its application was studied as a magnetically recyclable nanocatalyst in carbon-carbon coupling reactions between a wide range of aryl halides and butyl acrylate, methyl acrylate, acrylonitrile, phenylboronic acid, or 3,4-difluorophenylboronic acid under the conditions of a phosphine-free ligand and an air atmosphere. This catalyst has the advantages of both the Fe3O4 nanoparticles and mesoporous MCM-41. The structure of the catalyst was characterized via TEM, SEM, EDS, WDX, N-2 adsorption-desorption isotherm, XRD, TGA, FT-IR, and AAS. Also, the recovered catalyst was characterized via SEM, AAS and FT-IR. All the products from the carbon-carbon coupling reaction were obtained with excellent yields and high TON and TOF values, which indicate the high efficiency and activity of this catalyst. The selectivity of this catalyst was studied with various aryl halides bearing different functional groups. Furthermore, the heterogeneity and stability of Pd-imi-CC@MCM-41/Fe3O4 was studied via AAS, and leaching and poisoning tests. According to the results, this heterogeneous catalyst can be reused several times.

Various bromophenylalkenes were reductively photodebrominated by using 1,3-dimethyl-2-phenyl-1H-benzo-[d]imidazoline (DMBI) and 9,10-dicyanoanthracene. With deuterated DMBI analogs (the most effective was DMBI-d(11)), satisfactory to excellent isotopic yields were obtained. DMBI-d(11) could also be regenerated from the reaction mixtures with a recovery rate of up to 50%. The combination of the photodebromination reaction with conventional methods for bromoalkene synthesis enables sequential monodeuteration of a double bond without the necessity of a metal catalyst.

The direct oxidation of alcohols to esters is an environmentally benign and cost-effective organic synthetic strategy, but it is still a great challenge to discover an economic, highly active, and long-term stable catalyst for efficient transformation of alcohols to esters under milder conditions. Herein, we developed cobalt and copper nanoparticle -co-decorated nitrogen-doped carbon catalysts (CoCu@NCn) through two steps of ball milling and calcination. It was found that CoCu@NCn could catalyze the oxidation of alcohols to esters effectively in the absence of basic additives. The catalytic activity was much higher than those of monometallic Co@NC2 and Cu@NC2 samples, and the catalyst can be conveniently recovered and quite steadily reused. Through a series of control experiments and characterizations, it is concluded that the remarkable catalytic performance of CoCu@NC2 was associated with the synergistic effect between the two metal components, the enhanced basic active sites and the active surface area.

Treatment of 2-arylbenzoic acids with N-chlorosuccinimide (NCS) and NaI at 70 degrees C under fluorescent lighting condition gave the corresponding 3,4-benzocoumarins in good yields under transition-metal-free condition. It was found that the reactivity of NCS with NaI for the formation of 3,4-benzocoumarins from 2-arylbenzoic acids was as high as that with NIS. Thus, the formation of carboxyl radicals and their cyclization onto an aromatic ring from 2-arylbenzoic acids with much less expensive NCS and NaI, than NIS could be successfully carried out to form 3,4-benzocoumarins.

We found that in situ generated cerium(IV) carboxylate generated by mixing the precursor Ce((OBu)-Bu-t)(4) with the corresponding carboxylic acids served as efficient photocatalysts for the direct formation of carboxyl radicals from carboxylic acids under blue light-emitting diodes (blue LEDs) irradiation and air, resulting in catalytic decarboxylative oxygenation of aliphatic carboxylic acids to give C-O bond-forming products such as aldehydes and ketones. Control experiments revealed that hexanuclear Ce(IV) carboxylate clusters initially formed in the reaction mixture and the ligand-to-metal charge transfer nature of the Ce(IV) carboxylate clusters was responsible for the high catalytic performance to transform the carboxylate ligands to the carboxyl radical. In addition, the Ce(IV) carboxylate cluster catalyzed direct lactonization of 2-isopropylbenzoic acid to produce the corresponding peroxy lactone and gamma-lactone via intramolecular 1,5-hydrogen atom transfer (1,5-HAT).
