Novel triarylphosphine-functionalized imidazolinium salts have been prepared and successfully applied in palladium-catalyzed hydroarylation of bicyclic olefins. Under reductive conditions (HCOOH, Et3N), the complexes generated in situ from imidazolinium salts and Pd(OAc)(2) catalyzed the hydroarylation of bicyclic alkenes with aryl iodides, providing the hydroarylation products with high turnover numbers (TON, up to 1.9.10(5)) and turnover frequencies (TOF, up to 6.3.10(4)).
