In addition to being important synthetic reagents, ruthenate and perruthenate are of interest because they are representative of a number of high valent transition metal ions that can be used as oxidants in organic chemistry. In their reactions with alcohols both ions exhibit several striking similarities — concave Hammett plots, primary deuterium isotope effects, small enthalpies of activation, and large negative entropies of activation. The most likely explanation of the concave upward Hammett plots is the involvement of free radical-like transition states that could be formed by the decomposition of organometallic intermediates. Keywords: oxidation, ruthenate, perruthenate, alcohols, mandelic acid.

Oxidation of alcohols has industrial importance as it yields several useful products.Toxic and costly metal ions like Os(VIII), Cr(VI), and Ru in different oxidation states are widely used for the oxidation of a variety of organic compounds. We are reporting herein the oxidation of the industrially useful primary alcohols, 2-Chloroethanol, 2-Butoxyethanol and 2-Phenoxyethanol using Ammonium metavanadate in acidic medium. Relatively less toxic and cheaper transition metal ions of the first series are effectively used as homogeneous catalysts for the oxidation of the alcohols to the corresponding aldehydes. 2- Chloroethanol is used as a precursor for ethylene oxide and is useful in the manufacture of crop protection chemicals, and pharmaceuticals.2-Butoxyethanol finds use in the making of paints, varnishes and industrial and household cleaners.
