Synthesis, Electrochemical Behavior, and Catalytic Activity of Cobalt Complexes of 5,10,15,20-Tetraaryl-5,15-diazaporphyrinoids

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 cycliz...

Description
Summary: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-CoIII–alkyl radical intermediates.
