Nucleophilic reactivity of a mononuclear cobalt(iii)–bis(tert-butylperoxo) complex

Abstract

A mononuclear cobalt(III)–bis(tert-butylperoxo) adduct (CoIII–(OOtBu)2) bearing a tetraazamacrocyclic ligand was synthesized and characterized using various physicochemical methods, such as X-ray, UV-vis, ESI-MS, EPR, and NMR analyses. The crystal structure of the CoIII–(OOtBu)2 complex clearly showed that two OOtBu ligands bound to the equatorial position of the cobalt(III) center. Kinetic studies and product analyses indicate that the CoIII–(OOtBu)2 intermediate exhibits nucleophilic oxidative reactivity toward external organic substrates.
