Efficient Synthesis of 1,1-Diaryl 1,2-Dienes via Pd(0)-Catalyzed Coupling of Aryl Halides with Allenic/Propargylic Zinc Reagents. -The title reaction is proposed to involve oxidative addition of halides to Pd(0) to form an organopalladium intermediate. This is trapped by an allenic or propargylic z
