摘要

Abstract: Cationic manganese (II1) complexes qf the salen ligand [N," ethylenebis (salicylideneaminato)] are effective catalysts for the epoxidation of various olefins with iodosylbenzene as the terminal oxidant. The presence of electron-withdrawing groups, such as 5, s'-dichloro or-dinitro substituents, enhances the catalytic activity of the (sa1en) Mn"'catalyst in measure with the electron-deficient character of the cationic complex as ...
