摘要：

Dimerization of styrene was co-catalyzed with the different palladium complexes and Cu(OTf)(2) in ionic liquid BMImPF(6), in which Pd(OAc)(2)/Cu(OTf)(2) was found the best catalyst system. When molar ratio of Pd(OAc)(2)/Cu(OTf)(2) was 1/1 similar to 4/1, both high catalytic activity and selectivity were obtained. The Pd(OAc)(2)/Cu(OTf)(2) catalyst system has excellent solubility in ionic liquid BMImPF(6), and can be easily separated from the product. The results of dimerization of alpha-methylstyrene indicate that no products were detected at room temperature and it is benefieial to the reaction to raise temperature.
