of a series of sulfonium salts containing transferable diazomethyl groups is described, and the structure of these compounds is elucidated by X‐ray crystallography. Under photochemical conditions, reaction of these salts with N,N‐dialkyl hydrazones affords 1‐(dialkylamino)‐1,2,3‐triazoles via diazomethyl radical addition to the azomethine carbon followed by intramolecular ring closure. The straightforward
描述了一系列含有可转移重氮甲基的锍盐的一锅法合成,并通过 X 射线晶体学阐明了这些化合物的结构。在光化学条件下,这些盐与N , N -二烷基腙反应,通过重氮甲基自由基加成到偶氮甲碱碳上,然后进行分子内闭环,得到 1-(二烷基氨基)-1,2,3-三唑。还报道了由此获得的结构直接转变为介离子卡宾-金属配合物,并表征了这些新配体的供体性质。
