Synthesis and Characterization of cis‐A2B‐Type meso‐Triaryl‐Substituted Corroles
A practical synthesis of cis-A2B-type 5,10,15-triarylcorroles has been developed that involves [2+2]-type acid-catalyzed condensation of 5-aryldipyrromethane and 5-(pentafluorophenyl)dipyrromethane-1-carbinol and subsequent 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (DDQ) induced oxidative cyclization. All the corroles thus synthesized were structurally well-characterized, and their optical and electrochemical properties were also studied.
