Abstract

A one-pot synthesis of cobalt(II) complexes of 5,10,15,20-tetraaryl-5,15-diazaporphyrins (CoTADAPs) from the corresponding 5-aryl-1-arylamino-9-chlorodipyrrins and cobalt(II) acetate is reported. The CoTADAPs exhibited characteristic electrochemical behavior and catalyzed the intramolecular cyclization of N-benzyl-N-Boc-3-diazopropan-1-amines, probably via σ-Co^III-alkyl radical intermediates.
