Abstract:An oxidovanadium(IV) complex having a perrhenato ligand VO(ReO4)(4,4′-tBubpy)2]0.25SO4·0.5ReO4] (4,4′-tBubpy = 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 <em>meso</em>-1,2-diaryl-1,2-ethanediols under atmospheric molecular oxygen, affording the corresponding carbonyl compounds in good yield.</td>
