Popis:	The metal exchange reactions of Cd(II)-5,10,15,20-tetra(2,6-dichlorophenyl) porphyrin and Cd(II)5,10,15,20-tetra(2,6-difluorophenyl) porphyrin with Zn(II) and Co(II) cations in dimethylformamide were studied by the spectrophotometric method. The kinetic parameters of the metal exchange reaction were calculated and a possible stoichiometric mechanism of the process is proposed. The metal exchange reactions of 2,6-dihalogenated cadmium porphyrins with Zn(II) and Co(II) chlorides and acetates in dimethylformamide were investigated by the sampling method. Zn(II)- and Co(II)-complexes with 5,10,15,20-tetra(2,6-dichlorophenyl)porphyrin and 5,10,15,20-tetra(2,6-difluorophenyl) pophirin were synthesized and identified by UV-Vis, 1H NMR spectroscopy and mass spectrometry methods.
