Abstract
Methyl, phenyl and 1-alkenyl isothiocyanates 1 can react with diazomethane to give the corresponding 5-amino-1,2,3-thiadiazoles 4. In the presence of an excess of diazomethane these thiadiazoles rearrange to 1-substituted-5-(methylthio)-1H-1,2,3-triazoles 3. Reaction of 1-alkenyl isothiocyanate 1a with hydrazoic acid yields the corresponding 5-(1-alkenylamino)-1,2,3,4-thia-triazole 11, which does not rearrange when treated with diazomethane.
