Molecules. 2017 Nov 9;22(11):1941. doi: 10.3390/molecules22111941.

Abstract

A one-pot synthesis of bulky bis-pocket A₃B-type meso-cyano porphyrin, 5-cyano-10,15,20-tris(2,4,6-triphenylphenyl)porphyrin, has been accomplished via trifluoroacetic acid (TFA) catalyzed condensation of pyrrole and 2,4,6-triphenylbenzaldehyde in an acceptable yield of about 4%. DDQ served as oxidant and the cyanating agent.

Keywords: One-pot synthesis; meso-cyano porphyrin; pyrrole-aldehyde condensation; trifluoroacetic acid.
