A convenient procedure for the synthesis of 5-(4-acetamidophenyl)-10,15,20-
tris(4-substituted phenyl) porphyrins from dipyrrolomethane is reported, me
so-(4-Substituted phenyl) dipyrrolomethanes were obtained in yields of 72-8
4%. The amide porphyrins were isolated with appreciable yields of 15-17%.
