The kinetics of complexation between porphyrins and zinc acetate in acetonitrile was studied for the porphyrins belonging to various structural groups, including aza-, benzo-, and distorted N- and multiply substituted macrocycles. The effects of the distortion, on the one hand, and the enhanced rigidity of a macrocycle, on the other, on the complexation process were considered. The coordination of the distorted porphyrins to metal salts is facilitated because of the disturbance of the steric component of the macrocyclic effect (MCE), whereas the complexation of the rigid macrocycles is facilitated because of the activation of the electronic component of MCE.
