In the present study, an efficient, convenient, and green process for Suzuki-Miyaura and copper-free Sonogashira CC coupling reactions catalyzed by the heterogenous catalyst [PdCl2Ph2P)2N(CH2)3Si(OMe)3}] immobilized on Fe3O4@SiO2 nanoparticles is described. The magnetic nanocatalyst, [PdCl2Ph2P)2N(CH2)3Si(OMe)3}]/Fe3O4@SiO2 (2), was easily recovered with an external magnetic field and reused at least
本研究提出了一种高效、便捷、绿色的多相催化剂[PdCl 2 Ph 2 P) 2 N(CH 2 ) 3 Si(OMe)催化的Suzuki-Miyaura和无铜Sonogashira C C偶联反应的方法。描述了固定在Fe 3 O 4 @SiO 2纳米颗粒上的3 }] 。磁性纳米催化剂[PdCl 2 Ph 2 P) 2 N(CH 2 ) 3 Si(OMe) 3 }]/Fe 3 O 4 @SiO 2(2),很容易用外部磁场回收,并重复使用至少六次,没有明显的浸出或催化活性损失。此外,这种环保方法是使用 H 2 O/EtOH 等生物溶剂和微波辐射开发的,确保反应时间短。
