Investigating Ligand Sphere Perturbations on Mn^III-Alkylperoxo Complexes.

ABSTRACT: Manganese catalysts that activate hydrogen peroxide carry out several different hydrocarbon oxidation reactions with high stereoselectivity. The commonly proposed mechanism for these reactions involves a key manganese(III)-hydroperoxo intermediate, which decays via O-O bond heterolysis to generate a Mn(V)-oxo species that institutes substrate oxidation. Due to the scarcity of characterized Mn^III-hydroperoxo complexes, Mn^III-alkylperoxo complexes are employed to understand factors that affect the mechanism of the O-O cleavage. Herein, we report a series of novel complexes, including two room-temperature-stable Mn^III-alkylperoxo species, supported by a new amide-containing pentadentate ligand (^6Medpaq^5NO2). We use a combination of spectr
