摘要
一 ligand 免费哎呀反应催化由在产生 situ 的钯，在 PEG-400 的 nanoparticles 被开发了。这个催化系统是为在温和条件下面的芳基卤化物的 Heck 反应的一个简单、活跃的协议。比较实验证明 Heck 反应由钯 nanoparticles 催化在在 Heck 反应条件下面产生 situ 比那快很被执行由在里面前产生 situ 的。
A ligand-free Heck reaction catalyzed by in situ-generated palladium nanoparticles in PEG-400 has been developed.This catalytic system is a simple and active protocol for the Heck reaction of aryl halides under mild conditions.Comparative experiments demonstrated that the Heck reaction catalyzed by the palladium nanoparticles in situ-generated under the Heck reaction conditions was carried out much quicker than that by the in ex situ-generated ones.
