An oxidovanadium(IV) complex having a perrhenato ligand: An efficient catalyst for aerobic oxidation reactions of benzylic and propargylic alcohols

摘要

An oxidovanadium(IV) complex having a perrhenato ligand [VO(ReO4)(4,4'-(t)Bubpy)(2)][0.25SO(4)center dot 0.5ReO(4)] (4,4'-(t)Bubpy = 4,4'-di-tert-butyl-2,2'-bipyridine) efficiently catalyzes not only dehydrogenative oxidation of benzylic and propargylic mono-alcohols but also oxidative C-C bond cleavage of meso-1,2-diaryl-1,2-ethanediols under atmospheric molecular oxygen, affording the corresponding carbonyl compounds in good yield.
