B(C6F5)3-catalyzed allylation of propargyl acetates with allylsilanes

An efficient method for the B(C6F5)(3)-catalyzed allylation of secondary propargylic alcohol derivatives with allylsilanes has been developed. This method allows for the facile synthesis of a variety of 1,5-enynes in good to high yields with a number of functionalities, such as nitro, chloro, ester, and boronic ester, being tolerated under the reaction conditions.
