The reactions of silyl-substituted homoallyl alcohols with aryl halides under palladium catalysis result in regiospecific and stereoselective allyl transfer from the alcohols to aryl halides, offering modular synthesis of (E)-3-aryl-1-alkenyl-, (E)-1-aryl-2-alkenyl-, and optically active (E)-1-aryl-2-butenylsilanes.
