Abstract
The synthesis of cadmium chelates through an electrochemical technique, involving
the anodic oxidation of a sacrificial metallic electrode (cadmium) within an H-type
cell, is reported. This process utilizes acetonitrile as a solvent with organic
compounds containing abstractable hydrogen RH2 (nitroethane, 2-nitropropane, malononitrile
and diethylmalonate) serving as the reactants. This study encompasses the coordination
complexes of cadmium with ligands, 2,2′-bipyridine (bipy) or 1,10-phenanthroline
(phen).
The electrochemically synthesized products have been confirmed through various physical
measurements, elemental analyses and infrared spectral studies. This one-step electrochemical
technique is highly effective in obtaining metal complexes and their coordination
complexes. The determination of current efficiency for these synthesized complexes
serves to elucidate the underlying reaction mechanism.
