Remarkable selectivity in the cyclopropanation reactions catalysed by an halogenated iron meso-tetraphenylporphyrin
Iron(II) meso-tetra(2',6'-dichlorophenyl)porphyrin, Fe-II(TDCPP) catalyses the cyclopropanation of styrenes by ethyldiazoacetate with high yields and remarkable anti selectivities. The reaction mechanism is discussed and compared with that for the rhodium. catalysts. Some evidences for the presence of a radical intermediate in the iron catalysed reactions are also discussed.
