超声辐射下无铜无胺无膦Pd(OAc)_2体系中进行Sonogashira偶联反应,建立了适用于碘代芳烃的Sonogashira芳基化反应的合成方法,此法具有反应条件温和、反应时间短、收率高的优点。
Sonogashira coupling reaction was carried out in the copper-free amine-free and phosphine-free Pd (OAc) 2 system under ultrasonic irradiation. The synthetic method for Sonogashira arylation of iodoarenes was established. The method has the advantages of mild reaction conditions, short reaction time, The advantages of high yield.
