Interaction between meso-Phenyl-Substituted Porphirinioids and Carboxylic Acids, and a Thermal Analysis of Their Cationic Salts

Abstract: Thermogravimetry and quantum chemistry, including NBO analysis, are used to study the thermal stability and NH acidity of single and double protonated forms of tetrapyrrole macroheterocyclic ligands (porphyrins, their inverted and N-substituted analogs, and corroles). The temperature ranges of the destruction of porphyrinium acetates and trifluoroacetates, the enthalpies of evaporation of acid molecules from the crystalline phase, and the composition of cationic salts are calculated. The structures of protonated forms of macrocycles are optimized. The energies of porphyrin–acid interaction and the values of charge transfer ??during the formation of bonds are calculated.

SYNTHESIS OF N-CYANOPORPHYRINS AND RELATED COMPOUNDS. CRYSTAL STRUCTURE OF N-CYANO-MESO-TETRATOLYLPORPHYRIN.

N-Cyano-tetraphenylporphyrin was prepared either from N,N'-ethoxymethylene-meso-tetraphenylporphyrin and hydroxylamine-O-sulfonic acid or by direct cyanation with cyanogen bromide.Its metallation is rapid and concommitant cleavage of the N-substituent was observed.Such a reactivity can be used for rapid introduction of short-lived radionuclides into porphyrins.The crystal structure of N-cyano-meso-tetra-p-tolylporphyrin was determined.The macrocycle is ruffled, the pyrrole bearing the cyano group is tipped out of the (4N) plane by 29.3 deg.The angle of the cyanogroup with the corresponding pyrrole is 150 deg.
