摘要
A combination of tetrachlorosilane（TCS） and phenol in dichloromethane was found to be an efficient reagent for hydro-chlorination ofα,β-unsaturated ketones to afford the correspondingβ-chloroketones in good yield at ambient temperature. Reactions of the titled compounds with TCS-NaN_3 as well as with nitriles utilizing TCS-ZnCl_2 to give 1,5-disubstituted tetrazole derivatives orβ-amido ketones respectively are also described.
