Abstract

In this work, an anchored Pd complex (PGS-APTES-Pd(OAc)) was prepared simple and green steps from the natural clay mineral palygorskite and was well characterized by XPS, XRD, IR, SEM, and EDX. This complex was further utilized as a fine catalyst for the C-C/C-N coupling reactions of pyrimidin-2-yl sulfonates. Subsequently, the cyclic utilization test indicated the high stability and sustainability of this PGS-APTES-Pd(OAc) catalyst, and no activation was required in the recycling process, providing an applicable and reusable catalyst in organic synthesis.

摘要

在本工作中，通过简单且绿色的步骤，由天然粘土矿物坡缕石制备了一种锚定钯配合物（PGS-APTES-Pd(OAc)），并通过XPS、XRD、IR、SEM和EDX对其进行了充分表征。该配合物进一步用作嘧啶-2-基磺酸酯的C-C/C-N偶联反应的优良催化剂。随后，循环利用测试表明该PGS-APTES-Pd(OAc)催化剂具有高稳定性和可持续性，并且在循环过程中无需活化，为有机合成提供了一种适用且可重复使用的催化剂。
