A Pd-catalyzed method was developed for cross-coupling reaction of a wide range of alkynes with allylic alcohol in ionic liquids. In the presence of PdBr2, [Bmim]Br and HBraq, the cross-coupling products can be obtained in moderate to good yields, and the reaction displayed high regio-and stereo-selectivities. The catalyst system could be recycled four times without loss of activity.

Key words: ionic liquid, palladium-catalyst, alkyne, allylic alcohol, cross-coupling reaction
