Oxidation of benzoin catalyzed by oxovanadium(IV) schiff base complexes

BACKGROUND The oxidative transformation of benzoin to benzil has been accomplished by the use of a wide variety of reagents or catalysts and different reaction procedures. The conventional oxidizing agents yielded mainly benzaldehyde or/and benzoic acid and only a trace amount of benzil. The limits of practical utilization of these reagents involves the use of stoichiometric amounts of corrosiv...

Synthesis, structure and reactivity of oxovanadium(IV) schiff base complexes

Oxovanadium(IY) complexes with schiff bases, viz., N,N'-bis(2-hydroxy benzylidene)benzidine (HBB), N,N'-bis(2hydroxy benzylidine)-p-phenylenediamine (HBP) and cinnamylidene-2-aminophenol (CAPh) have been synthesized and characterized by elemental analysis, molar conductance, electronic spectra, Fr-IR, IH-NMR, ESR, FAB mass, thermal and magnetic susceptibility measurements. FAB mass and thermal ...

Sn(IV) Compounds Interaction with Metal-Schiff Base Complexes

The formation constants and Gibbs free energy for the interaction of RnSnClm (n = m = 2, R = Me, Ph, n-Bu or n = 4, m = 0, R = Ph) compounds as acceptors, with ML complexes (H2L = N,N'-bis(salicylidene)-2-aminobenzylamine (salabza-H2) and its derivatives, M = Mn2+ or Zn2+), as donors in N,N'-dimethylformamide (DMF) as solvent were studied. These parameters were measured by using UV-vis spectrop...
