ABSTRACT

The electrochemical dissolution of a sacrificial Cadmium (Cd) anode in a solution of tetrabutylammonium chloride (Bu4NCl) as a supporting electrolyte in acetonitrile (AcN) with different aldehydes/ketones forms the corresponding M(OCRR1)2 complexes in 1:2 molar ratio in high yield. (M= Cd, R= H in aldehydes, alkyl/aryl in ketones, R1= alkyl/aryl group). With Ligand L (1,10-phenanthroline or 2,2'-bipyridyl) these complexes conform to general formula M(OCRR1)2.L and all these synthesized complexes have been characterized by elemental analyses, infrared spectral data and other physical measurements. The results also show that direct electrosynthesis of the metal complexes have high current efficiency, purity and electrolysis yield.

Keywords: Electrochemical synthesis, Cadmium glycolates, Coordination compounds, 1,10-Phenanthroline (phen), 2,2'-Bipyridyl (bipy).
