Abstract

Condensation of a 5,5-disubstituted-dipyrromethanes (6a, 6b) with a 1,9-diformyl-pyrromethane (7) under MacDonald conditions in the presence of zinc(II) acetate affords zinc(II) salts (8a, 8b) possessing the isoporphyrin chromophore, which is stable with respect to transformation into porphyrin; some spectroscopic properties of (8a) and (8b) are described. © 1992.
