ELECTROCARBOXYLATION OF ORGANIC COMPOUNDS WITH CARBON DIOXIDE CATALYZED BY METALLOPORPHYRINS(Ⅰ)——CATALYTIC ACTIVITIES OF METALLOPORPHYRINS FOR ELECTROCARBOXYLATION OF BENZYL CHLORIDE

摘要

The electrocarboxylation of benzyl chloride with CO2 catalyzed by metalloporphyrins and the effects of different kinds of central metals and ligands on catalytic activities are reported. These metalloporphyrins whose central metals can form corresponding M （Ⅰ） complexes such as CoTPP, FeTPP have high activities. With water-soluble porphyrin ligands such as TPPS, TTMAPI, the corresponding metalloporphyrins have high catalytic activity. Electron-with-drawing groups on the porphyrin ring cause the lowering of activity.
