Synthesis of ruthenium(III) and osmium(III) porphyrin mono-alkyl and -aryl complexes and of a noval six-coordinate asymmetrically substituted ruthenium(IV) porphyrin complex, [Ru(oep)(Ph)(Me)]

Abstract

M^III porphyrin monoalkyl complexes, [M(oep)(Me)](M = Ru, Os), are produced by methylation of the monomer monoanion, [M(oep)]^–, or by additaion of MeMgBr to the [M(oep)]₂²⁺ dimer dication; the Ru^III monophenyl complex, [Ru(oep)(Ph)], can be reduced by one electron and treated with Mel to give the six-coordinate asymmetrically substituted Ru^IV porphyrin complex, [Ru(oep)(Ph)(Me)].
