Abstract
It is shown that α-chloro-γ-formyloctaethylporphyrin and porphyrins that contain a cyclopentane ring are formed along with monoformyloctaethylporphyrin and α,γ-diformyloctaethylporphyrin in the Vilsmeier formylation of the Co complex of octaethylporphyrin. Two crystalline modifications of the Zn complex of octaethylporphyrin were obtained, and their UV and IR spectra were studied.
