Sulfuryl diazide or sulfuryl azide is a chemical compound with the molecular formula SO2(N3)2. It was first described in the 1920s when its reactions with benzene and p-xylene were studied by Theodor Curtius and Karl Friedrich Schmidt.[1][2][3] The compound is reported as having "exceedingly explosive, unpredictable properties" and "in many cases very violent explosions occurred without any apparent reason".[1]
It was not until 2011 that sulfuryl diazide was isolated in a pure enough state to be fully characterized.[4] It was characterized by infrared and Raman spectroscopy; its structure in the solid state was determined by x-ray crystallography.[4] Its melting point is -15 °C.[4] It was prepared by the reaction of sulfuryl chloride (SO2Cl2) with sodium azide (NaN3) using acetonitrile as solvent:
Sulfuryl diazide has been used as a reagent to perform reactions that remove nitrogen from heterocyclic compounds:[5][6][7]
