Popis: Complexes of the type (NHC)Pd(PR3)I2 with bulky N-heterocyclic carbenes (NHC) are efficient catalysts for aryl coupling reactions such as the Suzuki and Stille cross-coupling reaction. These catalysts combine the advantageous stability of bis(carbene) complexes and the good activity of the bis(phosphine) complexes in these reactions. Both arylbromides and arylchlorides can be used as substrates.
