✦ Synopsis

Condensation

of a 5,5-disubstituted-dipyrromethanes 16~ 6bl with a 13d$ormylpyrromethane ( 7) under MacDonald conditions in the presence of zinc(H) acetate affords zinc(U) salts (Sa, 8b) possessing the isoporphyrin chromophore, which is stable with respect to transformation into porphyrin; some spectroscopic properties of (Sal urtd /8bI are described.
