Article Description

A mononuclear dioxo vanadium(V) complex of a hydrazone ONO donor ligand, [VO(L)] (1), was synthesized by the reaction of VO and terephthalic acid with HL in 1:1:1 mol ratio, while an oxo-bridged bis(vanadium(IV)oxo) complex, [μ -O-{VO(L)}] (2), was synthesized by the treatment of isonicotinic acid hydrazide, salicylaldehyde and CoSO·7HO with bis(acetylacetonato)oxovanadium(IV) (HL = isonicotinic acid(2-hydroxy-benzylidene)-hydrazide, HL = isonicotinic acid (1-methyl-3-oxo-butylidene)-hydrazide). The complexes were characterized by elemental analyses and spectroscopic methods. The crystal structure of complex 2 was determined by X-ray analysis. The complexes were tested as catalysts for the oxidation of cycloalkenes and benzyl alcohol using H O as terminal oxidant. Excellent selectivity was achieved in the oxidation of cyclohexene. © 2013 Springer Science+Business Media Dordrecht.
