The organic polymer and alumina anchored vanadyl and molybdenyl complexes were found to be effective for the oxidation of benzoin with fert-butylhydroperoxide as oxidant. With some of the catalysts only benzil was formed, whereas
with others three products, benzil, methyl benzoate and benzoic acid, were formed. The anchored molybdenum complexes were observed to be better catalysts than anchored vanadium complexes for the oxidation of benzoin. With the organic polymer anchored MoO,(salphen) catalyst, 89% of benzoin to benzil was formed. The effect of ligand, metal and support on the catalytic activity for the oxidation of benzoin has been studied.
