Abstract:Microelectrode voltammetry is used to investigate the mechanism for the catalysis by Co(II)(salen) of the reduction of n-butyl iodide, n-butyl bromide and 1,2-dibromobutane in DMF and the influence of electrolyte on these reactions. It is shown that when the ratio of alkyl halide to Co(II)(salen) in the solution is large, the voltammetry is quite different with each of the three alkyl halides and depends on the choice and concentration of electrolyte. The voltammetric characteristics can only be understood in terms of mechanisms which include additional steps to those proposed previously in the literature.
