Cyclopalladated Ferrocenylimine: Highly Active Catalyst for the Suzuki Reaction of Aryliodides with Phenylboronic Acid

Transition-metal catalyzed reaction represents an extremely versatile method in organic synthesis. [1] Searching for highly efficient catalysts has been the aim of organic chemists. Palladium catalyzed coupling of aryl halides with arylboronic acids, Suzuki reaction, is one of the most powerful methods for carbon-carbon bond formation. [2] Here we report the high efficiency of cyclopalladated ferrocenylimine 1 for the Suzuki coupling reaction of aryl iodides with phenylboronic acid. Excellent yields and high turnover numbers were obtained under optimized conditions after repeated uses (Schemes 1, 2).……
