Directly Linked Corrole Oligomers via Facile Oxidative 3–3′ Coupling Reaction

Abstract

Abstract Upon heating with p-chloranil in CHCl3, 5,10,15-tris(pentafluorophenyl)corrole (1H) underwent regioselective oxidative coupling reaction at the 3,3′-position to give dimer 2H and trimer 3H. Oxidation of 2H with p-fluoranil gave tetramer 4H and hexamer 6H. The crystal structures have been revealed for 2H, cobalt(III) complexed trimer 3Co·py6, and tetramer 4Co·py8.
