PdCl2 catalyzed carbon–carbon bond formation (Heck reaction) between substituted aryl halides and olefins was carried out without a ligand, under irradiation with UV–visible light. The results demonstrated that UV–visible light accelerated the rate of the reaction, leading to an excellent yield of corresponding products. The recovered palladium nanoparticles could be thermally recycled several times. PdCl2 gave excellent conversion up to the fifth addition of substrate.
PdCl2催化的芳基卤化物和烯烃之间的碳-碳键形成(Heck反应)在无配体条件下,在紫外可见光照射下进行。结果表明,紫外可见光加速了反应速率,导致相应产物的优良产率。回收的钯纳米颗粒可以在热条件下多次循环利用。PdCl2在第五次底物加入时给出了优异的转化率。
