The reaction of iron(III) and cobalt(III) porphyrin perchlorates with trimethylsilyldiazomethane

Abstract

The reaction of perchloratoiron(III) and -cobalt(III) octaethylporphyrins with trimethylsilyldiazomethane afforded N,metal-methano bridged organometalloporphyrins which further reacted with the carbene to give N(21),N(22)- and N(21),N(23)-ethano bridged porphyrin hydroperchlorates, selectively.
