Suzuki cross-coupling reactions of aryl chlorides using [Cl2Pd(COD)]/piperazine derivative under microwave conditions

A new strategy to significantly improve the efficiency of Suzuki reactions was achieved under microwave irradiation. [Cl2Pd(COD)]/piperazine derivative 1 catalyzed aryl chlorides with phenylboronic acid in methanol (50%) affording excellent yields under aerobic conditions. Application of this strate...

Zusammenfassung:	A new strategy to significantly improve the efficiency of Suzuki reactions was achieved under microwave irradiation. [Cl2Pd(COD)]/piperazine derivative 1 catalyzed aryl chlorides with phenylboronic acid in methanol (50%) affording excellent yields under aerobic conditions. Application of this strategy to the synthesis of liquid crystal material is also described. Copyright © 2011 John Wiley & Sons, Ltd. [Cl2Pd(COD)]/piperazine derivative‐catalyzed aryl chlorides afforded excellent yields under microwave irradiation. Application of this strategy to the synthesis of liquid crystal material is also described, with high isolated yield (95%) in just 10 min.
