Abstract
The structures of the products of the polyformylation of Cu, Ni, and Co complexes of etioporphyrin (EP) as monoformyl-, α,γ-diformyl-, α,β-diformyl-, and α,β,γ-triformyl-EP were established by electronic, IR, and PMR spectroscopy and mass spectrometry. α-Formyl-γ-(N-methylformaldimine)-EP and porphyrins that contain a cyclopentane ring can be formed by alkaline treatment of the Vilsmeier formylation products.
