Mononuclear Manganese(III) Superoxo Complexes: Synthesis, Characterization, and Reactivity.

ABSTRACT: Metal-superoxo species are typically proposed as key intermediates in the catalytic cycle of dioxygen activation by metalloenzymes involving different transition metal cofactors. In this regard, while a series of Fe-, Co-, and Ni-superoxo complexes have been reported to date, well-defined Mn-superoxo complexes remain rather rare. Herein, we report two mononuclear Mn^III-superoxo species, Mn(BDPP)(O₂^•-) (2, H₂BDPP = 2,6-bis((2-(S)-diphenylhydroxylmethyl-1-pyrrolidinyl)methyl)pyridine) and Mn(BDP^BrP)(O₂^•-) (2', H₂BDP^BrP = 2,6-bis((2-(S)-di(4-bromo)phenylhydroxyl-methyl-1-pyrrolidinyl)methyl)pyridine), synthesized by bubbling O₂ into solutions of their Mn
