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.
In aqueous / ionic liquids, an efficient and unsupported PdCl 2 -catalyzed method for Suzuki-Miyaura and Mizoroki-Heck reaction has been developed and a good coupling yield has been obtained.At the same time, PdCl_2 / K_2CO_3 / H_2O / ionic liquids The reaction system can be directly reused 3 to 5 times without activation, and this unloaded and recyclable method extends to the formation of other C-C bonds.
