A robust magnetic nanoparticle-supported N-heterocyclic carbene-palladacycle has been readily synthesized by 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 times without obvious loss of activity highlighting the efficiency of our strategy of immobilization of previledged catalysts.

磁性纳米粒子支撑的N-杂环卡宾-Palladacycle：一种有效且可回收的固体分子催化剂，用于9-氯ac啶的Suzuki-Miyaura交叉偶联

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。
