Imidazole-1-sulfonyl azide hydrogen sulfate is presented as an efficient reagent for the synthesis of sulfonyl azides from primary sulfonamides. The described method is experimentally simple and high-yielding and does not require the addition of Cu salts. Furthermore, 15N NMR mechanistic studies show the reaction proceeds via a diazo transfer mechanism. Imidazole-1-sulfonyl azide hydrogen sulfate provides

Direct synthesis of sulfonyl azides from sulfonic acids
A one-pot process for the synthesis of various sulfonyl azides (RSO2N3) by treating sulfonic acids with triphenylphosphine/trichloroisocyanuric acid/sodium azide at room temperature is described. A wide range of arenesulfonyl and alkanesulfonyl azides was obtained in excellent yields under mild conditions.[GRAHPICS].
