Ionic and Radical Substitution in Cobaltadithiolene Ring Induced by Dibenzoyl Peroxide

Abstract

Abstract The reaction of (η5-cyclopentadienyl)(1,2-ethenedithiolato)cobalt(III) complexes with dibenzoyl peroxide at moderate temperature (40 °C) brings about the substitution of a benzoyloxy group for a hydrogen in the cobaltadithiolene ring in an ionic mechanism. At 110 °C in a toluene solution, the substitution of a benzyl group for a hydrogen in the cobaltadithiolene ring in a radical mechanism occurs competitively with benzoyloxylation.
