摘要：

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. (C) 2001 Elsevier Science Ltd. All rights reserved.
