Abstract
The reaction of “spanned” zinc porphyrin with organic peroxides in the presence of pyridine at 298 K was studied. The kinetic characteristics of the reaction were obtained. The presence of pyridine favors the formation of the zinc chlorin complex. The nature of the nitrogen base affects the character and rate of the reactions of the zinc porphyrin with peroxide. The structures of the sterically strained metal porphyrin and of the chlorin complex formed in the reaction were optimized by PM3 calculations. As follows from the geometric structure of the macrocyclic compounds, the deformations of the macroring enhance in going from zinc porphyrin to zinc chlorin.
