PVC-NHC-Pd(0) catalyst was prepared and exerted to highly cis-selective semihydrogenation of diarylacetylene using formic acid as hydrogen source under mild condition. The as-prepared catalyst was well characterized by various techniques such as FT-IR, 1H NMR, XRD, SEM, EDX, TEM, XPS, and TGA. The catalyst can be easily recovered and recycled without loss of its activity and selectivity owing to the
制备了PVC-NHC-Pd(0)催化剂,在温和条件下,以甲酸为氢源,实现了二芳基乙炔的高顺式选择性半氢化反应。所制备的催化剂通过各种技术如 FT-IR、1 H NMR、XRD、SEM、EDX、TEM、XPS 和 TGA进行了很好的表征。由于 Pd(0) 与聚合 NHC 配体之间的金属-配体相互作用,该催化剂可以很容易地回收和再循环而不会损失其活性和选择性。该方案是经典 Lindlar 氢化的一种有吸引力的替代方案。
