The coupling reaction of aryl and vinyl iodides, bromides, and triflates with organostannanes can be effectively conducted using palladium on carbon as a source of Pd0. The yield and rate of reaction are significantly affected by the addition of copper iodide as co-catalyst and triphenylarsine as ligand.
使用钯/碳作为Pd 0的来源,可以有效地进行芳基和乙烯基碘化物,溴化物和三氟甲磺酸酯与有机锡的偶联反应。加入碘化铜作为助催化剂和加入三苯基s作为配体会显着影响反应的收率和反应速率。
