摘要
在水/离子液体中,发展了一种高效、无负载Pd Cl_2催化Suzuki-Miyaura和Mizoroki-Heck反应的方法,并且得到较好的偶联产率.同时,Pd Cl_2/K_2CO_3/H_2O/离子液体组成的反应体系无需活化可以直接重复使用3~5次.这种无负载和可循环的方法可延伸到其它C—C键的形成.
Efficient and unsupported protocols were developed for Pd Cl_2-catalyzed Suzuki-Miyaura and Mizoroki-Heck reactions using water/ionic liquid systems to afford the cross-coupling products with excellent yields.It is noteworthy that the Pd Cl_2/K_2CO_3/water/ionic liquid systems can be recovered and used for 3~5 cycles directly.The results suggest that the unsupported and recyclable systems can be extended to the other realm of C—C bond formation.
