Abstract The Suzuki coupling was carried out using a new, efficient and reusable polymer-supported Pd/IL catalyst (PEt@IL/Pd) under aqueous conditions. This catalyst was prepared through coacervation approach followed by treatment with Pd(OAc)2. The FT-IR, SEM, TGA, TEM, XPS, ICP and EDX techniques were employed to characterize the PEt@IL/Pd. This catalyst exhibited high activity in the Suzuki coupling reaction under green conditions. Moreover, the catalyst could be recycled and reapplied for six times with no appreciable loss in its activity. The leaching test also showed high stability of catalytic Pd species under applied conditions.

含离子液体的聚乙烯负载钯：一种绿色、高效、稳定的铃木反应催化剂

摘要 Suzuki 偶联是在水性条件下使用一种新型、高效且可重复使用的聚合物负载的 Pd/IL 催化剂（PEt@IL/Pd）进行的。该催化剂通过凝聚方法制备，然后用 Pd(OAc) 2 处理。采用 FT-IR、SEM、TGA、TEM、XPS、ICP 和 EDX 技术来表征 PEt@IL/Pd。该催化剂在绿色条件下的 Suzuki 偶联反应中表现出高活性。此外，该催化剂可以循环使用六次，其活性没有明显损失。浸出试验还显示了在应用条件下催化 Pd 物种的高稳定性。
