Burgess reagent, i.e. methyl N-(triethylammonium sulfonyl)carbamate, is an internal salt of the carbamate class used as a water-losing agent in organic chemistry Chemicalbook. It is soluble in most organic solvents. It is commonly used in the reaction of cis-elimination of secondary and tertiary alcohols into alkene, and the reaction is mild and selective. However, the primary alcohol reaction is not effective.
