We straightforwardly synthesized 18 different types of palladium nanoparticles by using a series of palladium metal precursors and ionic liquids. All the materials went for XRD, TEM, and ICPOES analysis, before going to Heck cross-coupling reaction as a catalyst. We evaluated the catalytic performance of our developed IL#Pd MNP catalyst over Heck cross-coupling reaction between different terminal olefins with various 3-iodo-benzopyrones, including sterically hindered, electron-rich, electron neutral and electron-deficient systems. We obtained the Heck cross-coupling reaction product in good to average yield under phosphine free reaction condition with an added advantage of 6 times catalyst recycling.

离子液体介导的钯纳米催化剂中的Heck交叉偶联反应

我们使用一系列钯金属前体和离子液体直接合成了18种不同类型的钯纳米颗粒。在进行Heck交叉偶联反应作为催化剂之前,所有材料都要进行XRD,TEM和ICPOES分析。我们评估了我们开发的IL#Pd MNP催化剂在不同末端烯烃与各种3-碘-苯并吡喃酮之间的Heck交叉偶联反应(包括位阻,富电子,电子中性和电子不足的系统)上的催化性能。我们在无膦反应条件下以良好的平均收率获得了Heck交叉偶联反应产物,并具有6倍的催化剂循环利用优势。
