Abstract

A simple straightforward synthesis of N3S, N2S2, N2O2, N2SO and N2OS porphyrins and an improved method for the synthesis of an N3O porphyrin with one meso-unsubstituted carbon atom are reported from readily available precursors. The reactivity of the meso-unsubstituted carbon atom was demonstrated by carrying out bromination followed by Heck coupling reactions.
