be used as a versatile reagent in organic synthesis. Primary and secondary alcohols are converted to their carbonyl compounds, α-hydroxy ketones to their diketones, and hydroquinones to their quinones. Aromatic amines are converted to their azo compounds, benzylamine to benzaldehyde, phenylhydrazones and oximes to their carbonyl compounds. Thiols are also converted to their disulfides in high yields
Cp(2)Sm(thf)(2) was found to be an efficient catalyst for the acylation of alcohols and amines with esters under mild conditions. In the present acylation, vinyl and isopropenyl acetates served as good acylating agents. Thus, a variety of alcohols and amines underwent acylation with vinyl and isopropenyl acetates in the presence of Cp(2)Sm(thf)(2) to give the corresponding esters and amides in good

shown that this reagent is capable of oxidizing organic substrates, converting alcohols to their corresponding carbonyl compounds, aromaticamines to their corresponding azo compounds, hydroquinone to p-benzoquinone, benzylamine to benzaldehyde, and triphenylphosphine to its oxide in good yields. Saturated hydrocarbons, unsaturated hydrocarbons, unsaturated ketones, and saturated amines are not affected

Sodium tungstate was found to be an active and highlyselective catalyst to oxidation of various primary or secondary origin renewable alcohols by hydrogenperoxide as green oxidant. Borneol, nerol, geraniol and β-citronellol were efficiently and selectively converted to respective carbonyl derivatives by hydrogenperoxide. ATR/FT-IR measurements confirmed that Na2W(O2)4 was the specie active catalytically
