Liquid Azide Salts (Preprint)

Ionic liquid azides from azidoethyl, alkyl and alkenyl substituted derivatives of 1,2,4- and 1,2,3-amino-triazoles, were prepared and examined for the first time in order to investigate their structural and physical properties. All reported salts possess melting points below 100 C. The unique character of these newly discovered ionic liquid azides is based upon the fact that these molecules are not simple protonated salts like previously reported substituted hydrazinium azides. The presence of quaternary nitrogen confers both thermal stability and negligible volatility.
