With the aid of HClO{sub 4} as proton and BPh{sub 4}{sup -} as electron source, the Fe complex of a pentadentate pyridyl-appended cyclam ligands can activate dioxygen to yield the corresponding oxoiron(IV) complex (see scheme; TMC-py=1-(2'-pyridylmethyl)-4,8,11-trimethyl-1,4,8,11-tetraazacyclotetradecane; C gray, Fe magneta, N blue, O red). This transformation is proposed to occur via a hydroperoxoiron(III) intermediate.
