Abstract:
Oxovanadium(V) compounds serve as Lewis acids with oxidation capability and induce one-electron oxidative transformations of organosilicons, organotins, organoaluminums, organoborons, organozincs, and/or their ate complexes. Low-valent vanadium-catalyzed stereoselective reductive transformations, including dehalogenation, pinacol coupling, and the related radical reaction, have been developed by constructing a multicomponent redox system in combination with a coreductant and an additive.
Keywords: low-valent vanadium; Oxidation; oxovanadium; radical; reduction; synthetic reaction.
