Abstract
The Vilsmeier formylatlon of the cobalt complex of 5,10,15,20-tetraphenylporphyrin was realized, and its intermediate salt with the dimethylformamide-POC13 complex was isolated; demetallation of the latter gave 1-formyl-5,10,15,20-tetraphenylporphyrin. Formyltetraphenylporphyrin oxime and its 0-acetyl derivative and 1-cyano-5,10,15, 20-tetraphenylporphyrin were synthesized. The Wittig reaction with formylporphyrin and its copper and cobalt complexes with methoxycarbonylmethinyltriphenylphosphorane and diethylamidocarbonylmethinylhexamethyltriamidophosphorane was realized, and conditions that affect the ratios of the Z and E isomers of the acrylic derivatives obtained were studied.
