reaction of various 1,2,4-oxadiazoles with an excess of hydrazine in DMF has been investigated. 3-Amino-1,2,4-triazoles are produced through a reductive ANRORC pathway consisting of the addition of hydrazine to the 1,2,4-oxadiazole followed by ring-opening, ring-closure, and final reduction of the 3-hydroxylamino-1,2,4-triazole intermediate. The general applicability of 1,2,4-oxadiazoles ANRORC reactivity
已经研究了各种1,2,4-恶二唑与过量肼在DMF中的反应。3-氨基-1,2,4-三唑是通过还原性ANRORC途径生产的,该途径包括向1,1,2,4-恶二唑中添加肼,然后进行开环,闭环和最后还原3-的过程。羟氨基-1,2,4-三唑中间体 1,2,4-恶二唑类ANRORC反应性的一般适用性也在没有C(5)链接的吸电子基团的情况下得到证明。
