A novel PEPPSI (pyridine enhanced precatalyst preparation stabilization and initiation) type palladium(II) complex has been synthesized and fully characterized by NMR, HR-MS, as well as elemental analysis. The molecular structure was finally confirmed by single crystal X-ray diffraction, and it revealed that the pyridyl-armed 1,2,3-triazole ligand is coordinated to the palladium in bidentate fashion. This air and moisture insensitive complex has proven to be a suitable catalyst for the arylation of pyridine N-oxides and 2-bromopyrroles with a broad functional group tolerance, demonstrating that the robustness and high efficiency of our complex.

合成了一种新型的PEPPSI（吡啶增强的前催化剂制剂的稳定和引发作用）型钯（II）配合物，并通过NMR，HR-MS和元素分析对其进行了全面表征。最终通过单晶X射线衍射确认了分子结构，并且揭示了吡啶基武装的1,2,3-三唑配体以二齿形式与钯配位。这种对空气和湿气不敏感的复合物已被证明是适合N-吡啶氧化物和2-溴吡咯芳基芳基化的合适催化剂，具有宽泛的官能团耐受性，证明了该复合物的坚固性和高效性。
