Synthesis and redox behavior of dialkylated dicobalt complexes having two discrete salen units

Novel dialkylated dicobalt complexes with two discrete salen units have been synthesized and characterized by UV–vis, NMR, and ESI-mass spectroscopies as well as elemental analyses. Redox behavior of the complexes was investigated by means of cyclic voltammetry and ESR spin-trapping techniques. The results indicate that cobaltcarbon bonds cleave homolytically to produce the radical species during the electrolysis.
