分析试剂氮是一种介离子化合物，其结构由阳离子三唑单元和阴离子PhN取代基组成。我们提供了明确的证据，证明存在单线态二氨基碳化合物互变异构体，其结构是由具有NHPh取代基的1,2,4-三唑-5-酰基单元组成的。
The analytical reagent Nitron is a mesoionic compound whose structure consists of a cationic triazolium unit with an anionic PhN substituent. We provide clear evidence for the existence of a singlet diaminocarbene tautomer whose structure is composed of a 1,2,4-triazol-5-ylidene unit bearing an NHPh substituent.
