highly efficient cross couplings of aryl bromides and chlorides with AlAr3(THF) (Ar = Ph, 2,4,6-Me3C6H2, 2-naphthyl or 4-Me3SiC6H4) catalyzed by the economic palladium catalyst of PCy3 are reported without the use of a base and under mild reaction conditions at room temperature or temperatures < or = 60 degrees C even for couplings of bulky aryl halides and the Al(2,4,6-Me3C6H2)3(THF) reagent.
报道了经济上使用PCy3钯催化剂催化的芳基溴化物和氯化物与AlAr3(THF)(Ar = Ph,2,4,6-Me3C6H2,2-萘基或4-Me3SiC6H4)的新型高效交叉偶联。即使在庞大的芳基卤化物与Al(2,4,6-Me3C6H2)3(THF)试剂偶合的情况下,也可以在室温或低于或等于60摄氏度的温和反应条件下,在温和的反应条件下制备。
