Isomeric type 1 and 2 amino-1,2,4-triazoles condensed with thiazole, thiazine and thiazepine rings were synthesised from 5-amino-2,3-dihydro-1H-1,2,4-triazol-3-thione and α,ω-dihaloalkanes through the 5-amino-3-(ω-haloalkylthio)-1H-1,2,4-triazole intermediates. The reaction conditions leading to derivatives 1 and 2, respectively, were determined. A general and safe method for the unambiguous differentiation
由5-氨基-2,3-二氢-1 H -1,2,4-三唑-3-硫酮和α,ω-二卤代烷烃通过5-氨基-3-(ω-卤代烷硫基)-1 H -1,2,4-三唑中间体。确定分别导致衍生物1和2的反应条件。结构1和2的cmr光谱提供了一种用于区分结构1和2的通用且安全的方法。
