N²-Selective autocatalytic ditriazolylation reactions of cyclopropenones and tropone with N¹-sulfonyl-1,2,3-triazoles are reported for the first time. In contrast to previous methods for preparing N²-substituted bis(1,2,3-triazolyl) compounds, the present reaction achieved ditriazolylation in one step under simple and user-friendly conditions with a wide substrate scope. A plausible mechanism has been proposed relying on preliminary mechanistic investigations.

N2-磺酰基-1,2,3-三唑类化合物的环丙烯酰胺和丁酮的N2-选择性自催化二重氮唑化反应

首次报道了环丙烯酮和托酮与N ^1-磺酰基-1,2,3-三唑的N ^2-选择性自催化二三唑基化反应。与先前制备N ^2-取代的双（1,2,3-三唑基）化合物的方法相反，本反应在简单且用户友好的条件下以宽的底物范围在一步中实现了二三唑基化。已经提出了一种可能的机制，该机制依赖于初步的机械研究。
