The invention provides a high yield/isomerically pure synthesis of new 1-amino-3-substituted-1,2,3-triazolium salts and their subsequent transformation into isomerically pure 1-substituted-1,2,3-triazoles. These new 1-amino-3-substituted-1,2,3-triazolium salts are easily isolated and can be stored at ambient conditions with no degradation or isomerization. These quarternary salts are easily converted with appropriate silver salts to a wide array of new quarternary salts with various anions, with many of these new salts having melting points below 100 C, classifying them as ionic liquids. Subsequent diazotization of these 1-amino-3-substituted-1,2,3-triazolium salts results in high yields of isomerically pure 1-substituted-1,2,3-triazoles, that until this invention were problematic to make pure without tedious reagents or workup procedures. Both classes of materials (1-amino-3-substituted-1,2,3-triazolium salts as well as 1-substituted-1,2,3-triazoles) should be of high interest as these classes of materials are known to be very important pharmaceutical materials for a wide array of medical and agricultural applications as well as possible propellant applications.
这项发明提供了新的1-氨基-3-取代-1,2,3-三唑盐的高产率/异构纯合成,以及它们随后转化为异构纯的1-取代-1,2,3-三唑。这些新的1-氨基-3-取代-1,2,3-三唑盐易于分离,并且可以在常温条件下存储而不会发生降解或异构化。这些季铵盐可以很容易地与适当的银盐转化为各种带有不同阴离子的新的季铵盐,其中许多这些新盐的熔点低于100摄氏度,可归类为离子液体。随后对这些1-氨基-3-取代-1,2,3-三唑盐进行重氮化反应,可以高产率地得到异构纯的1-取代-1,2,3-三唑,这在这项发明之前是难以纯净制备的,需要繁琐的试剂或工作程序。这两类材料(1-氨基-3-取代-1,2,3-三唑盐以及1-取代-1,2,3-三唑)应该具有很高的研究兴趣,因为这些材料类别被认为是非常重要的药用材料,可用于广泛的医药和农业应用,以及可能的推进剂应用。
