(Methoxycarbonylsulfamoyl)triethylammonium Hydroxide

[29684-56-8] C8H18N2O4S (MW 238.35) InChI = 1S/C8H18N2O4S/c1-5-10(6-2,7-3)15(12,13)9-8(11)14-4/h5-7H2,1-4H3 InChIKey = YSHOWEKUVWPFNR-UHFFFAOYSA-N (dehydration agent1) Alternate Name: Burgess reagent. Physical Data: mp 76–79 °C. Solubility: sol benzene, toluene, THF, triglyme, acetonitrile, dichloromethane. Form Supplied in: colorless solid. Preparative Method: although the Burgess reagent is commercially available, it can be easily synthesized in two steps:1a the reaction of anhydrous methanol with Chlorosulfonyl Isocyanate followed by the addition of Triethylamine affords the reagent in good yield. Handling, Storage, and Precautions: moisture sensitive; the use of anhydrous solvent and atmosphere in reactions with this reagent is recommended.
