An easily available Pd(OAc)2/(2-mesitylindenyl)dicyclohexylphosphine/Me(octyl)3N+Cl−/K3PO4·3H2O catalytic system was developed and it shows high catalytic activity in the Suzuki–Miyaura cross-coupling reaction of a diverse array of aryl and heteroaryl chlorides in water. Notably, this catalytic system also works with ultra-low loading of the catalyst with high turnover numbers.
容易获得的Pd(OAc)2 /(2-异丁烯基)二环己基膦/ Me的(辛基)3 Ñ +氯- / K 3 PO 4 ·3H 2 ö催化体系被开发,它示出了在芳基和杂芳基氯化物的多样性阵列的Suzuki-Miyaura交叉偶联反应的高催化活性水。值得注意的是,该催化系统还可以在超低负荷下以高周转数运行。
