A robust, selective, and highly efficient method for the preparation of 1,3,4-triaryl 1,2,3-triazolium salts has been developed. It features arylation of a click triazole with a diaryliodonium salt in the presence of a copper catalyst under neat conditions. The presence of pyridine functionality is tolerated, enabling the first access to key precursors of pyridyl-mesoionic carbene ligands. The method
已经开发了一种强大,选择性和高效的方法来制备1,3,4-三芳基1,2,3-三唑鎓盐。它的特征是在纯净条件下,在铜催化剂存在下,单击三唑与二芳基碘鎓盐的芳基化作用。吡啶官能团的存在是可以容忍的,从而可以首次接触到吡啶基-mesoionic卡宾配体的关键前体。该方法已被整合到一锅方案中,其中末端炔烃,叠氮化钠和二芳基碘鎓盐为起始化合物。
