Good yields of 2,2-dialkyltriazanium sulfates were obtained by reaction of hydroxylamido-O-sulfuric acid or its sodium salt with 1,1-dialkylhydrazines. Thus N,N-diaminopiperidinium sulfate and N,N -diamino-α-pipecolinium sulfate could be prepared for the first time. Reaction of these compounds with various barium salts in aqueous solution led to the corresponding triazanium salts due to precipitation of barium sulfate. The structure of these substances were verified by NMR and IR spectroscopic data and elementary analysis. Analogous syntheses of triazanium salts from mono-, 1,2-di-, tri- and tetramethylhydrazine were not successful.
