Kinetics and mechanism of chromium(III)-catalysed oxidation of ethane-l,2-diol and propane-l,2-diol by cerium(IV) in aqueous sulfuric acid media

Investigations on the equilibrium chemistry of Cu" and Zn"-2-pyridinccarboxaldchydc (A)-L-valinc, L-phenylalaninc and DL-tryptophanc (B) systems show that in the M(AB), M(AB)A and M(AB)2 type of complexes, the Schiff basc(AB) binds in a ferdentate manner.
