Cycloalkeno-1,2,3-thiadiazoles (3a–d) can be prepared from cycloalkanone-tosylhydrazones (2a–d) by treatment with SOCl2. Oxidation of 3a–d with peracetic acid yields 1,2,3-thiadiazole-2-oxides (4a–d) and 1,2,3-thiadiazole-1,1,2-trioxides (5a–c). A characterisation of these three classes of compounds is performed by discussion of their UV, IR, NMR and mass spectra.
环烯烃-1,2,3-噻二唑(3a–d)可以通过用SOCl 2处理从环烷酮-甲苯磺酰hydr(2a–d)制备。用过氧乙酸氧化3a–d生成1,2,3-噻二唑-2-氧化物(4a–d)和1,2,3-噻二唑-1,1,2-三氧化物(5a–c)。通过讨论它们的UV,IR,NMR和质谱图,可以对这三类化合物进行表征。
