Abstract


Acid and base properties of series of β -substituted derivatives of tetraphenylporphyrin are studied in present work. First and second stage ionization constants for investigated ligands are determined. Acid properties of porphyrins are found to be in good agreement with classical theories about influence of substituent’s nature and geometrical structure of macrocycle on their physical and chemical parameters. It is found that whole investigated porphyrins have catalytic activity in heterogeneous oxidation of N,N-diethylcarbamodithioate.
