摘　　要：Electrochemical catalytic reactions of tetraphenylporphmatocobalt were studied in DMF and EtCl2 solutions in the presence of 1,2 dibroraoethane and 1,2-dichloroethane utilizing cyclic voltamme-try, thin-layer electrochemistry, in situ UV-visible spectroelectrochemistry and computer digital simulation methods. Homogeneous rate constants for reactions of electrogenerated Co(Ⅰ)TPP species with 1,2-dibro-moethane and 1,2-dichloroethane were determined as 1. 2×103 and 5 mol-1 · dm3 × s-1, respectively. Neither alkylation nor degradation of CoTPP was observed.Electrochemical catalytic reactions of tetraphenylporphmatocobalt were studied in DMF and EtCl2 solutions in the presence of 1,2 dibroraoethane and 1,2-dichloroethane utilizing cyclic voltamme-try, thin-layer electrochemistry, in situ UV-visible spectroelectrochemistry and computer digital simulation methods.
