| Abstract: | Metal exchange of cadmium 5,10,15,20-tetraphenylporphyrinate (CdTPP) and cadmium 2-bromo-5,10,15,20-tetraphenylporphyrinate (CdTPPBr) with zinc acetate in dimethylformamide was spectrophotometrically examined. The kinetic parameters of the metal exchange reaction were determined. A possible stoichiometric mechanism of the reaction was suggested. The effect of the bromo substituent in β-position of the pyrrole in the cadmium tetraphenylporphyrinate on the metal exchange reaction with Zn(OAc)2 in DMF was found. |
