Abstract:

The effects of peptides, amino acids and organic bases as axial ligands on reaction activities in the electrocarboxylation of benzyl chloride with CO2 catalyzed by CoTPP are reported. Imidazole, peptide containing -SH and amino acid containing imidazyl can enhance the catalytic activity. As an axial ligand, imidazole is the best one, it can make the current efficency of electrocarboxylation catalyzed by CoTPP rising about 23%. The effects of different amount of imidazole on CoTPP's catalytic activities have been studied, and the cause of these effects have been explaind preliminarily.

Key words: Metalloporphyrin, Electrocarboxylation, Catalytic activity, Axial ligand
