Chalcones silanes

With excess silane, further reduction of the saturated ketone to the corresponding saturated alcohol occurs in high yield. In the case of chalcones, excess silane may effect complete reduction and deoxygenation to yield the corresponding alkane. " " ... 

As shown in Scheme 5, the scope of the reaction with respect to the chalcone component is broad. Electron-withdrawing and electron-donating substituents are well tolerated and afford the 1,4-diketone in good yields. Interestingly, methyl vinyl ketone and ethyl acrylate are suitable partners in the acyl silane addition reaction.
