Methane sulfonyl azide Chemical Properties,Usage,Production
Uses
Methane sulfonyl azide is used as a diazo transfer reagent for activated methylene,[1] methine,[1,2] and methyl[3] groups; functionalization of double and triple bonds.
Preparation
Preparative Methods of Methane sulfonyl azide: reaction of Methanesulfonyl Chloride with Sodium Azide in MeOH(EtOH)/H2O[1,3] or acetone[2] (55-61 or 96% yields, respectively). By substituting acetone for methanol, the formation of MeSO2OMe is avoided and the reagent is obtained in >95% purity.
storage
Methane sulfonyl azide should be stored in the cold and the dark. Explosive when heated above 130 °C. No experimentalists have reported any difficulty handling MsN3, but proper caution should be used, as with all azide reagents. Use in a fume hood.
Purification Methods
Purification of Methane sulfonyl azide: crystallization from ether in dry-ice/acetone or from 95% EtOH at -75 °C; distillation in vacuo.
