Highly Efficient Route to <i>o</i>-Allylbiaryls via Palladium-Catalyzed Three-Component Coupling of Benzynes, Allylic Halides, and Aryl Organometallic Reagents

<i>o</i>-Allylbiaryl derivatives have been prepared in good to excellent yields by the palladium-catalyzed three-component reaction of allyl halides, benzynes, and aryl organometallic reagents.
