The synthesis of C-C bonds is considered one of the most fundamental challenges in both organic chemistry and the chemical industry, as these bonds are essential for the preparation of high-value products. Therefore, it is crucial to develop efficient, cost-effective, and environmentally sustainable methods for C-C bond formation. In this context, herein, a novel Schiff-base/Pd-functionalized Zr-based UiO-66 MOF (UiO-66/SB-Pd) is synthesized through a straightforward post-modification process and utilized as a highly efficient catalyst in the Suzuki C-C coupling reaction. The designed UiO-66/SB-Pd material was characterized by using FT-IR, EDX, PXRD, TGA, N adsorption-desorption and SEM analyses. This catalyst displayed remarkable catalytic performance and stability in the Suzuki coupling reaction, facilitating the synthesis of a wide range of biaryl compounds. The catalyst retained its activity after seven consecutive cycles. Moreover, a leaching test indicated the excellent stability of the Pd active species under the reaction conditions.
碳-碳键的合成被认为是有机化学和化学工业中最基本的挑战之一，因为这些键对于制备高价值产品至关重要。因此，开发高效、经济高效且环境可持续的碳-碳键形成方法至关重要。在此背景下，本文通过简单的后修饰过程合成了一种新型席夫碱/钯功能化的锆基金属有机框架材料（UiO-66/SB-Pd），并将其用作铃木碳-碳偶联反应中的高效催化剂。通过傅里叶变换红外光谱（FT-IR）、能谱分析（EDX）、粉末X射线衍射（PXRD）、热重分析（TGA）、氮吸附-脱附以及扫描电子显微镜（SEM）分析对所设计的UiO-66/SB-Pd材料进行了表征。该催化剂在铃木偶联反应中表现出卓越的催化性能和稳定性，有助于合成多种联芳基化合物。该催化剂在连续七个循环后仍保持其活性。此外，一项浸出试验表明钯活性物种在反应条件下具有出色的稳定性。
