A β-unsubstituted-β'-vinylporphyrin has been synthesized which reacted with an excess of acetylenedicarboxylate ester to give monobenzoporphyrins in high yield. Evidence that suggests an isomerization of the initial adduct to a new porphyrin enroute to the benzoporphyrin is presented.
Chemistry of Pyrrolic Compounds. LI. Porphyrins with Electron-Withdrawing Groups in the Same Pyrrolic Ring: Preparation of a Pyridazinoporphyrin

, p. 1185 - 1201 (2007/10/02)
The preparation and properties of porphyrins bearing electron-withdrawing groups in the same pyrrolic ring are described.The principal example studied is a diformylporphyrin and this has been used to prepare a porphyrin containing a fused pyridazine ring.The properties of this novel system are discussed.
