Activation of a high-valent manganese-oxo complex by a nonmetallic Lewis acid.

ABSTRACT: The reaction of a manganese(V)-oxo porphyrinoid complex with the Lewis acid B(C6F5)3 leads to reversible stabilization of the valence tautomer Mn(IV)(O)(π-radical cation). The latter complex, in combination with B(C6F5)3, reacts with ArO-H substrates via formal hydrogen-atom transfer and exhibits dramatically increased reaction rates over the Mn(V)(O) starting material.
