Application of dimeric cyclopalladated complex of tribenzylamine as an efficient catalyst in the Heck cross-coupling reaction

The activity of [Pd{C6H4(CH2N(CH2Ph)2)} (μ-Br)]2 complex was investigated in the Heck–Mizoroki C–C cross-coupling reaction. This complex is an active and efficient catalyst for the Heck reaction of aryl iodides, bromides and even chlorides and also arenesulfonyl chlorides. The cross-coupled products were produced in excellent yields in short reaction time using a catalytic amount of [Pd{C6H4(CH2N(CH2Ph)2) (μ-Br)]2 complex in NMP at 130 °C.

Also using catalytic amount of palladium complex in NMP at 130 C led to C-C bond formation and corresponding products were produced in good yields are other advantages of this manuscript. ► The reaction conditions is mild and the yields are high.
