interesting nickel-based catalyst supported on DABCO-functionalized silica was successfully prepared and evaluated as heterogeneous nanocatalyst in Heck cross coupling reaction of various aryl halides and methyl acrylate. The as-prepared nanocatalyst was well characterized by FT-IR, FE-SEM, TEM, XRD, SEM-EDX, ICP and TGA techniques and found to be highly efficient in the reaction system in terms of activity
摘要 成功制备了一种有趣的镍基催化剂,负载在 DABCO 功能化二氧化硅上,并作为多相纳米催化剂在各种芳基卤化物和丙烯酸甲酯的 Heck 交叉偶联反应中进行评估。所制备的纳米催化剂通过 FT-IR、FE-SEM、TEM、XRD、SEM-EDX、ICP 和 TGA 技术得到了很好的表征,并发现在活性和可回收性方面在反应体系中是高效的。图形摘要这项工作提供了一种基于镍纳米颗粒的经济且非均相催化系统,负载在 DABCO 功能化二氧化硅上,用于各种芳基卤化物与丙烯酸甲酯的 Heck 交叉偶联反应。
