Reversible formation of iodosylbenzene-iron porphyrin intermediates in the reaction of oxoiron(IV) porphyrin pi-cation radicals and iodobenzene

The electronic nature of iron porphyrin complexes and iodobenzene derivatives markedly influences the formation of iodosylbenzene-iron(III) porphyrin intermediates 2, which are generated in the reaction of oxoiron(IV) porphyrin cation radicals 1 and iodobenzene. Epoxidation of olefins by 2 affords high yields of epoxide products.close585
