Evidence for a reactive (alkene)peroxoiridium(iii) intermediate in the oxidation of an alkene complex with O2

Abstract

An (alkene)peroxoiridium(III) complex, [Ir(L)(cod)(O₂)] [where LH = PhNC(NMe₂)NHPh and cod = 1,5-cyclooctadiene], was identified as an intermediate in the reaction of the Ir^I precursor [Ir(L)(cod)] with O₂ and characterized by spectroscopic methods. Decay of the intermediate and further reaction with 1,5-cyclooctadiene produced 4-cycloocten-1-one.
