| Abstract: The catalytic action of transition metal chlorides (MnCl2,FcCl2,CoCl2,CuCl) with 2,2'-bipyridine in the liquid phase oxidation of cyclohexcnc was investigated.It was found that the catalytic activity,the induction period,the product distribution and the electronic spectra of catalyst system (MClx/bipyridc) were similar with that of the corresponding synthetic complexes M(bipy)n.The experimental result clearly indicated that transition metal chlorides can react with bipyride during the reaction and form a complex in situ which have catalytic activity for the oxidation of cyclohcxcne.The experimental result concerning the effect of various ligands on the catalytic activity showed that the catalytic activity of complex formed in situ relates with the basicity of ligands,and that the catalytic system consisted of mixed ligands (bipy with py or pip) is more active than that of catalytic system with single ligand (bipy or py or pip). |
