  • Abstract

    Electrochemical oxidation of a sacrificial aluminum anode with thiols (RSH) like ethanethiol, 2-propanethiol, 1-butanethiol, 2-methyl-2-propanethiol, 1-pentanethiol and thiophenol in the presence of tetrabutylammonium chloride as a conductive additive, acetonitrile as a solvent and platinum as a cathode yield aluminium(III) thiolates. Adducts of these compounds with ligand L (L= 1,10 phenanthroline and
    2,2-bipyridyl) have also been obtained by addition of these ligands to the electrolysis phase. These electrochemically synthesized products have been characterized by microanalysis, physical measurements and IR spectral studies. These have been identified as Al(SR)3 and Al(SR)3.L. All these products are associated with very high current efficiencies.
