A novel bis(pyridyl-functionalized 1,2,3-triazol-5-ylidene)-palladium(II) complex Pd(Py-tzNHC)2 catalyses the copper-, amine-, phosphine-, and additive-free aerobic Sonogashira alkynylation of (hetero)aryl bromides in water as the only reaction solvent. The catalysis proceeds along two connected Pd-cycles with homogeneous bis-carbene Pd(0) and Pd(II) species, as demonstrated by electrospray ionization mass spectrometry.
一种新型的双（吡啶官能化1,2,3 - 三唑 - 5 - 亚基）钯（II）配合物Pd(Py - tzNHC)₂在仅以水作为反应溶剂的条件下，催化（杂）芳基溴化物进行无铜、无胺、无膦且无添加剂的需氧Sonogashira炔基化反应。如电喷雾电离质谱所示，该催化反应通过均相双卡宾钯（0）和钯（II）物种沿着两个相连的钯循环进行。
