A novel and efficient synthesis of γ-alkynyl ketones by the direct nucleophilic substitution of propargyl alcohols with enoxysilanes in the presence of a catalytic amount of p-toluenesulfonic acid monohydrate, has been developed. The reactions can be performed in an undried solvent under an air atmosphere to obtain the desired products in good yields.

Key words: Keywords propargyl alcohol, enoxysilane, nucleophilic substitution, catalyzed, p-toluenesulfonic acid
