Abstract

Octaethyl-, 5-phenyloctaethyl-, 5,15-diphenyloctaethyl-, 5,10,15,20-tetraphenyloctaethyl, and dodecaphenylporphyrins were prepared, and their geometries were optimized by the method of molecular mechanics. The deformation of the porphyrin macroring grows as the number of phenyl groups is increased. The dissociation kinetics of the manganese, cobalt, and copper complexes of the porphyrins in solutions of sulfuric acid in acetic acid were studied. The kinetic parameters of the dissociation of metal porphyrins were analyzed in relation to the porphyrin structure and nature of the metal.
