Abstract
Kinetic measurements are reported for the dealkylation reactions of ammonium and sulphonium compounds and organic halides with cobalt(I) complexes of a series of tetradentate Schiff's bases. The reaction was followed by polarography and cyclic voltammetry. The kinetics conformed to a second order rate law and pseudo-first order plots were obtained in the presence of an excess of substrate. The plot of E½ values vs. log k″ for the reaction with PhBr and EtBr and [Me2SC6H4Me]+ shows a linear free energy relationship suggesting a simple SN2 displacement reaction and confirming that the nucleophilicity of cobalt(I) species is influenced by the nature of the chelating ligands.
