Synthesis of novel dinuclear cobalt complexes of 2+2 macrocyclic ligands with a bis(imino)pyridine moiety

摘要

Ligands with N-aryl bis(imino)pyridine moieties are redox-active so that it is possible to generate reduced states of metal complexes at higher potential. These complexes have been used as electrocatalysis1. On the other hand, dinuclear cobalt complexes of macrocyclic ligands with bis(imino)pyridine moieties were reported as catalysts for ethylene polymerization2.
