Aa. Elasmy et al., ELECTROCHEMICAL SYNTHESIS OF BENZOYLGLYCINE AND ETHYLPHTHALOYLGLYCINECOMPLEXES OF TRANSITION-METAL IONS, Transition metal chemistry, 19(6), 1994, pp. 603-605
The direct electrochemical oxidation of metallic iron, cobalt, nickel
and copper in Me(2)CO solution of benzoylglycine and/or ethylphthaloyl
glycine gave products with high yields. For each of the complexes, the
electrochemical efficiency is commensurate with the metals being diva
lent. Conventional physical and chemical studies were used to characte
rize the isolated complexes and octahedral geometry was suggested for
them on the basis of magnetic and electronic spectral studies. The i.r
. spectra show that the ligands coordinate in a bidentate fashion; the
carboxylate ion is monodentate. The molar conductances agree with the
complexes being non-electrolytes.
