摘要
以3-(2-苯基-1,2,3-三唑-4-基)-4-氨基-5-巯基-1,2,4-三唑(1)为原料分别与ω-溴代芳基乙酮、ω-溴代-ω-(1H-1,2,4-三唑-1-基)芳基乙酮反应,合成了一系列新的1,2,4-三唑[3,4-b]-1,3,4-噻二嗪类化合物2a~2e和3a~3e.其结构经IR,1HNMR和MS及元素分析确证.
A series of 1',2',4'-triazolo[3,4-b]-1,3,4-thiadiazines were synthesized by the reaction of 3-(2-phenyl-1,2,3-triazol-4-yl)-4-amino-5-mercapto-1,2,4-triazole with ω-bromoacetophenones or ω-bromo-ω- (1H-1,2,4-triazol-1-yl)acetophenones in EtOH at reflux. Their structures were characterized by elemental analysis, IR, ^1H NMR and MS spectra.
