Abstract

The nature of the anionic ligand X (X = EtOSO3, BF4, Cl, Br, OSO2CF3, F or CN) in vanadium(V)salen complexes [V+O(salen) X−] was found to have a significant influence on the catalytic activity of the complexes, but not on their enantioselectivities; with the complexes in which X = Cl or F being most active and the complex with X = OSO2CF3 being totally inactive.
