Selective Aerobic Oxidation of Benzylic Alcohols Catalyzed by a Dicyclopropenylidene-Ag(I) Complex

摘要

The unprecedented synthesis, single-crystal X-ray structure, and first catalytic application of a dicarbene- Ag(I) complex [Ag(BAC)(2)][CO2 CF3] (BAC = bis-(diisopropyl) aminocyclopropenylidene) is reported. This novel complex provides a versatile catalytic platform for selective aerobic oxidation of benzylic alcohols to aldehyde or ketone products in high yields. Ease of experimental execution coupled with the use as an oxidant and low catalyst loading are inherit strengths of these oxidations.
