Metal Exchange Reaction of Cd(II) 5,10,15,20-Tetra(4-chlorophenyl)porphyrinate with Copper and Zinc Chlorides in DMSO

The metal exchange reactions of Cd(II) 5,10,15,20-tetra(4-chlorophenyl)porphyrinate with CuCl2 and ZnCl2 in DMSO were studied by the spectrophotometric method. The kinetic parameters of the metal exchange reactions were determined. A possible reaction mechanism was proposed. Zinc(II) and copper(II) 5,10,15,20-tetra(4-chlorophenyl)porphyrinates were synthesized by the complex formation reactions of zinc(II) and copper(II) acetates with 5,10,15,20-tetra(4-chlorophenyl)porphyrin and by metal exchange of its cadmium complex with ZnCl2 and CuCl2 in dimethylformamide. The resulting compounds were identified by electronic absorption and H-1 NMR spectroscopy and mass spectrometry methods.
