Palladium-Catalyzed sp2-sp3 Coupling of Chloromethylarenes with Allyltrimethoxysilane: Synthesis of Allyl Arenes.

Palladium-catalyzed remote sp2-sp3 coupling reaction of chloromethylarenes with allyltrimethoxysilane is described in this work. The allylation reaction regioselectively occurred on the para-positions of 1-(chloromethyl)naphthalenes and benzyl chlorides to form new C(sp2)-C(sp3) bonds. The reaction proceeds smoothly under mild conditions to produce allyl arenes in moderate to excellent yields.
