1,2,3‐Triazolylidene‐based mesoionic carbene boranes have been synthesized in a convenient one‐pot protocol from the corresponding 1,2,3‐triazolium salts, base, and borane. Borenium ions are obtained by hydride abstraction and serve as catalysts in mild hydrogenation reactions of imines and unsaturated N‐heterocycles at ambient pressure and temperature.
基于1,2,3-三唑基亚烷基的中离子卡宾硼烷已通过便捷的一锅法从相应的1,2,3-三唑鎓盐,碱和硼烷中合成。硼离子是通过氢化物提取获得的,并在环境压力和温度下,在亚胺和不饱和N杂环的轻度加氢反应中用作催化剂。
