In the interest of designing versatile catalysts for one-electron small molecule activation reactions our group is exploring electronically flexible non-innocent ligands of metalloradical species. Bis(imino)-2,2'-bipyridyl ligand was synthesized and characterized by 1H NMR, 13C NMR and single-crystal X-ray diffraction. Late transitional metal complexes of the ligands were prepared from metal chloride salts and characterized by single-crystal X-ray diffraction. The coordination chemistry of these compounds was explored. One of the synthesized complexes, the cobalt bis(mesitylimino)-2,2'-bipyridyl complex, features cobalt coordinated to both bipyridine nitrogen donors and one imine donor with one free imine. The stability, redox properties, and reactivity with carbon monoxide will be described.
