The Burgess reagent (methyl N-(triethylammoniumsulfonyl)carbamate) is a mild and selective dehydrating reagent often used in organic chemistry. It was developed in the laboratory of Edward M. Burgess at Georgia Tech. The Burgess reagent is used to convert secondary and tertiary alcohols with an adjacent proton into alkenes. Dehydration of primary alcohols does not work well. The reagent is soluble in common organic solvents and alcohol dehydration takes place with syn elimination through an intramolecular elimination reaction. The Burgess reagent is a carbamate and an inner salt. A general mechanism is shown below. (Wikipedia).
We've seen one organometallic reagent before, the Grignard reagent. That had magnesium in it. Well now let's learn another! Organolithium reagents are commonly used, so let's see what they do. Watch the whole Organic Chemistry playlist: http://bit.ly/ProfDaveOrgChem General Chemistry Tut
