Abstract

A mononuclear nonheme manganese(III)-acylperoxo complex bearing a simple picolylamine-based linear ligand was synthesized and characterized by various spectroscopic methods along with theoretical calculations. The reactivity of the manganese(III)-acylperoxo complex was investigated in the oxygen atom transfer, C-H and O-H bond activation reactions. The oxidations of organic substrates followed first-order kinetics with respect to substrates and featured nonradical-type, suggesting that the manganese(III)-acylperoxo complex was the reactive oxidant. The C-H bond activation of hydrocarbon and the O-H bond activation of alcohol proceeded via a rate-limiting H-atom abstraction reaction in a concerted manner.
