A novel series of alkyne-containing potassium organotrifluoroborates were prepared in good yields from the corresponding haloaryltrifluoroborates and various alkynes via Sonogashira coupling reaction. Also, the Suzuki−Miyauracross-coupling reaction of alkynylaryltrifluoroborates with aryl and alkenyl bromides was achieved in the presence of 5 mol % of Pd(TPP)4 and 3.0 equiv of Cs2CO3 in aqueous 1
通过Sonogashira偶联反应,由相应的卤代芳基三氟硼酸酯和各种炔烃以高收率制备了一系列新的含炔烃的有机三氟硼酸钾。同样,在150° C的1,4-二恶烷水溶液中存在5 mol%的Pd(TPP)4和3.0当量的Cs 2 CO 3存在下,实现了炔基芳基三氟硼酸酯与芳基和烯基溴化物的Suzuki-Miyaura交叉偶联反应。C通过微波辐照。
