Abstract

A vitamin B12 derivative with a trifluoromethyl group as an axial ligand, heptamethyl trifluoromethylaquacobyrinate perchlorate, [[(CF3)(H2O)Cob(III)7C1ester]ClO4], is prepared and characterized by elemental analysis, 1H NMR, 19F NMR, ESI-MS, UV-vis absorption, and cyclic voltammetry. The Co-CF3 complex shows homolysis of the Co(III)-CF3 bond under visible light irradiation, which releases a CF3 radical that can be detected by a radical trapping experiment.
