The hydrogen atom transfer reactivity of a porphyrinoid cobalt superoxide complex

Abstract

The H-atom transfer (HAT) reactivity of a corrolazine cobalt superoxide with weak O–H and N–H substrates has been demonstrated. Kinetic analysis shows relatively fast rates of HAT with diphenylhydrazine (DPH). A kinetic isotope effect (KIE) and Eyring activation parameters are consistent with an HAT mechanism.
