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.
