by homogeneous Pd-catalyzed direct arylation is an important research topic in modern organic chemistry. In this study, PEPPSI-type, (PEPPSI = Pyridine Enhanced Precatalyst Preparation Stabilization and Initiation), new Pd-catalysts with N-heterocyclic carbene ligand were synthesized, and they were used as catalysts in the synthesis of bi(hetero)arenes by direct arylation process. The structures of
摘要 由于双(杂)芳烃在工业上的重要性,通过均相 Pd 催化直接芳基化合成这些化合物是现代有机化学中的一个重要研究课题。本研究合成了具有 N-杂环卡宾配体的新型 Pd 催化剂,PEPPSI 型(PEPPSI = Pyridine Enhanced Precatalyst Prepared Stabilization and Initiation),并将它们用作直接合成双(杂)芳烃的催化剂。芳基化过程。Pd-卡宾配合物的结构通过不同的光谱和分析技术,如NMR、FT-IR和元素分析来阐明。通过单晶 X 射线衍射研究确定了其中一种配合物的更详细的结构特征。
