摘      要：Polyaniline-supported tungsten(W@PANI)was easily prepared by immersing polyaniline(PANI)in the aqueous solution of *** was found to be an efficient catalyst for oxidative deoximation reaction,the very important transformation for pharmaceutical *** the green features,the method employed very few of catalytic tungsten(0.048 mol%*** substrates),resulting in the high turnover numbers(TONs)of the catalyst(ca.103 mol/mol)and the low metal residues in product(0.1 ppm).The reaction is applicable for a variety of substrates,including those containing heterocycles,which are key intermediates in medicine *** has also been successfully magnified to kilogram scale production to afford the desired carbonyl products smoothly.
