directly anchoring the structural defined acenaphthoimidazolylidene palladacycle with a long tail on magnetic nanoparticles (MNPs), and functioned as a solid molecular catalyst and exhibited extremely high catalytic activity towards the challenging Suzuki–Miyaura cross-coupling reactions between less-studied heterocyclic 9-chloroacridine and diverse boronic acids. Remarkably, the catalyst could be used 5
坚固的磁性纳米粒子支撑的N-杂环卡宾-Palladacycle已通过将结构明确的啶咪唑亚甲基Palladacycle与长尾巴直接锚定在磁性纳米颗粒(MNP)上而容易地合成,并且起着固体分子催化剂的作用,并且对碳纳米管表现出极高的催化活性。研究较少的杂环9-氯ac啶与各种硼酸之间的具有挑战性的Suzuki-Miyaura交叉偶联反应。值得注意的是,该催化剂可以使用5次而不会明显失去活性,这突出了我们固定化催化剂的策略的效率。
