Polymers containing the structure of N-heterocyclic carbenes (NHCs) have attracted much interest due to their superior complexing ability to metal ions and good recyclability, which make them promising candidates as solid supporters. Herein, we developed an easy method to synthesize polyimidazolium chloride salt (PImCl) via one-step method in mild conditions. After PImCl was chelated with palladium chloride in 3-chloropyridine, this NHC-Pd polymer was employed as the solid catalyst for Suzuki reactions of aryl bromides and phenylboronic acid. The catalytic activity of the NHC-Pd polymer was high for many different substrates. Moreover, the Suzuki reaction of 4-bromoanisole with phenylboronic acid could be catalyzed by this NHC-Pd polymer in mild conditions. Furthermore, this solid catalyst could be easily isolated by centrifugal separation. After several recycling runs, the catalytic activity decreased little. Compared with the conventional methods, this method was much simpler and more efficient, which showed enormous potential in preparing new heterogeneous supporter of porous polyimidazolium chloride salt.

含有N-杂环卡宾（NHCs）结构的聚合物因其与金属离子的出色络合能力和良好的可回收性而引起了人们的极大兴趣，这使其成为有前途的固体支持物。在这里，我们开发了一种简单的方法，可在温和条件下通过一步法合成聚咪唑氯化物盐（PImCl）。将PImCl与3-氯吡啶中的氯化钯螯合后，将该NHC-Pd聚合物用作芳基溴化物和苯基硼酸的Suzuki反应的固体催化剂。对于许多不同的底物，NHC-Pd聚合物的催化活性均很高。而且，该NHC-Pd聚合物在温和的条件下可以催化4-溴茴香醚与苯基硼酸的Suzuki反应。此外，可以通过离心分离容易地分离该固体催化剂。经过几次循环运行后，催化活性几乎没有下降。与常规方法相比，该方法简单，高效，在制备新型多孔聚咪唑氯化物异质载体方面显示出巨大的潜力。
