The equilibrium quotient of the adduct formation of [Co(Salen)PPh3]ClO4.H2O and [Co(7,7'-dimethylSalen)PPh3]ClO4.H2O, as acceptor with amines donors are studied by spectrophotometer. Thermodynamics of these pentacoordinate cobalt(III) Schiff-base complexes have been examined withn-butylamine,sec-butylamine,tert-butylamine, benzylamine and diethylamine in constant ionic strength of 0.1 M sodium perchlorate and acetonitrile solvent at room temperature. We aimed to investigate the effects of different electronic and steric situations of donor and acceptor by comparing their equilibrium quotient for any adduct.

A simple, highly efficient and mild catalytic oxidation of benzoins to the corresponding benzils was developed using manganese(II) Schiff base complexes as novel and reusable catalyst in the presence of acetonitrile as solvent and H2O2as green oxidant. This simple method affords benzil derivatives at room temperature in short reaction times with high yield and purity. This convenient procedure will allow a further increase of the diversity within the benzil family.
