Abstract

Acid dissociation constants in acetonitrile were determined for cationic forms of sterically strained tetraethyltetramethylporphyrin derivatives. These compounds are more basic than their unstrained analog because of deformations of the porphyrin macroring, that increase the electron density on tertiary nitrogen atoms of the reaction center and make them more accessible for reaction.
