Study of the metal-exchange reaction between Cd(II) octa(4-bromophenyl)tetraazaporphyrinate and cobalt chloride in organic solvents.

The metal-exchange reaction between Cd(II) octa(4-bromophenyl)tetraazaporphyrinate and cobalt chloride in dimethylformamide and dimethyl sulfoxide was studied by spectrophotometry. Kinetic parameters of the metal-exchange reaction were determined. A possible stoichiometric mechanism of the reaction was proposed. Cobalt(III) octa(4-bromophenyl)tetraazaporphyrinate was synthesized and characterized. [ABSTRACT FROM AUTHOR]
