We report a novel mesoionic N-heterocyclic olefin (mNHO) derived from a 1,2,3-triazolium salt. With the carbenic position unprotected, the mNHO can tautomerize into the mesoionic carbene (MIC) form at room temperature. The reactivity of this new mNHO with various group 13 Lewis acids and CO₂ have been studied experimentally and computationally.

未保护的介电N-杂环烯烃的反应性

我们报告了一种新型的介电N-杂环烯烃（mNHO）衍生自1,2,3-三唑鎓盐。在未保护羧基位置的情况下，mNHO可以在室温下互变异构为中离子卡宾（MIC）形式。已经通过实验和计算研究了这种新的mNHO与13族路易斯酸和CO ₂的反应性。
