Oxidation of alcohols using H2O2 to corresponding carbonyl compounds in good yields for lanthano-phosphotungstates catalysts and its recyclability up to five cycles was envisaged in water.

A “sandwich” type tungstophosphate, [Zn4(H2O)2(PW9O34)2]10–, was used as the efficient and reusable catalyst for alcohol oxidation. The catalyst I of K10Zn4(H2O)2(PW9O34)2·20H2O and the catalyst II of [(C18H37)2(CH3)2N]8K2[Zn4(H2O)2(PW9O34)2] were used to catalyze the oxidation of alcohols in water. High yields of the corresponding carbonyl compounds were obtained. The catalysts were recycled several times without loss in activity.

A major application of 2-Iodoxybenzoic acid (IBX) is the oxidation of alcohols to carbonyl compounds, at room temperature. IBX is insoluble in almost all solvents, except DMSO. IBX tolerates amine functionality and is therefore used for the oxidation of amino alcohols to amino carbonyl compounds. IBX oxidizes 1,2-glycols without the cleavage of the glycol carbon-carbon bond. Allylic and benzylic positions are also susceptible to oxidation by IBX. Synthesis of a,b-unsaturated carbonyl compounds from carbonyl compounds can be accomplished by using IBX as oxidant. Silyl enol ethers undergo oxidation upon exposure to IBX and 4-methoxypyridine N-oxide. Water-soluble derivatives of IBX, and polymer-based IBX, with additional advantages, have also been developed. IBX mediated transformations facilitate the construction of diverse heterocyclic systems.
