Previous studies in this laboratory have shown oxygen to be a crucial requirement for the reaction of methane with benzene over zeolite catalysts at 400°C in a high pressure batch reactor. Thus, a two-step mechanism involving the intermediate formation of methanol by partial oxidation of methane...
This catalytic system exhibited high performance with regard to the synthesis of methylated benzenes and gave high yields of total methylated products (up to 52% benzene‐based yield and 42% CO2‐based yield) under the reaction conditions employed in this study (pCO2 = 1 MPa; pH2 = 5 MPa;...

An improved procedure has been developed for the Rieche formylation of substituted benzenes using dichloromethyl methyl ether and silver trifluoromethanesulfonate. This reaction proceeds smoothly at low temperatures (78 to 0 °C) over sh... Kretchmer,A Richard - 《Journal of Organic Chemistry》 被...
A facile method for the synthesis of polycyclic indole derivatives: the generation and reaction of tungsten-containing azomethine ylides. Treatment of N-(o-alkynylphenyl)imine derivatives with W(CO)(5)(L) induces the 5-endo-mode of cyclization of the imine nitrogen onto the electrophilically .....
摘要: A mild, versatile and efficient method for the regioselective hydrodifluoromethylation of unactivated alkenes has been developed. This Ag-mediated Csp3–CF2bond forming reaction provides easy access to a variety of vicinal α-difluoroacetate-containing alkanes....
