Abstract
Binuclear metal-Schiff base complexes [Mn2(PA2ppd)2Cl4] (I), [Mn2(PA2mpd)2Cl4] (II) and a mononuclear complex [Mn(PA2opd)Cl2] (III) were synthesised and characterized. The complexes I-III were used as catalysts for the epoxidation of olefins with iodosylbenzene as an oxidant in acetonitrile-water solvent mixture. Binuclear complexes I and II selectively catalysed the epoxidation, whereas the mononuclear complex III was unselective. Among the binuclear, the complex having a m-phenyl-enediamine bridge was superior to the one with a p-phenylenediamine bridge as the catalyst for the epoxidation of olefins. The effect of addition of nitrogen bases on the catalytic activity of (II) was also studied.
