✦ Synopsis

In previous paperslp4 we described the formation and the identification in non--polar solvents of mixed ligand complexes some dithiocarbamate (DTC) complexes with different N-alkyl substituents according to the equation:

2 A similar exchange reaction was studied by other authors and the mixed ligand complexes were observed by nuclear magnetic resonance (NMR), electron paramagnetic resonance (EPR) and a.c. voltammetry5 -g. Moriyasu and Hashimotol",* l carried out kinetic and equilibrium high-performance liquid chromatographic (HPLC) studies of mixed ligand complexes formed from some dialkyl-DTC chelates of Ni(I1) and Cu(I1). Experimentally determined K values were found to be 4.0, the rate constants
