Abstract

Na12[WZn3(H2O)2[ZnW9O34)2], easily self assembled from Na2WO4 and Zn(NO3)2, catalyses the in situ oxidation of ammonia with hydrogen peroxide to hydroxylamine, which further reacts with ketones and aromatic aldehydes in an aqueous biphasic medium without organic solvent to yield oximes as valuable intermediates.
