Abstract
For 3,7,13,17-tetramethyl-2,8,12,18-tetrabutylporphyrin, 5,15-diphenyl-3,7, 13,17-tetramethyl-2,8,12,18-tetrabutylporphyrin, and the cyclophane dimer i n which the monomeric porphyrin fragments are bound via meta positions of t he benzene rings with two -O(CH2)(3)O- bridges, the kinetics of complexatio n with copper(II) acetate in acetonitrile and the base ionization in the pr esence of perchloric acid were studied. The reactivity of these compounds i n complexation with the metal cation in acetonitrile correlates with their basicity.
