The Burgess reagent (methyl N-(triethylammoniumsulfonyl)carbamate) is a mild and selective dehydrating reagent often used in organic chemistry. [1] [2] 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 ...
The classic example of a dehydration reaction is the Fischer esterification, which involves treating a carboxylic acid with an alcohol to give an ester RCO 2 H + R′OH ⇌ RCO 2 R′ + H 2 O Often such reactions require the presence of a dehydrating agent, i.e. a substance that reacts with water.
In organic chemistry, a condensation reaction is a type of chemical reaction in which two molecules are combined to form a single molecule, usually with the loss of a small molecule such as water. [1] If water is lost, the reaction is also known as a dehydration synthesis.
The compound is a reagent in organic synthesis. One application is for the dehydration of a secondary alcohol to give an alkene: [2] RCH(OH)CH 2 R' + Ph 2 S[OC(CF 3) 2 Ph] 2 → RCH=CHR' + Ph 2 SO + 2 HOC(CF 3) 2 Ph Mechanism of the dehydration using Martin's sulfurane.
used as a pigment and as a precursor to other manganese compounds; used as a reagent in organic synthesis for the oxidation of allylic alcohols Meta-Chloroperoxybenzoic acid: used as an oxidant in organic synthesis Methyl tert-butyl ether: a gasoline additive; also used in organic chemistry as a relatively inexpensive solvent Millon's reagent
Triflic anhydride is prepared by dehydration of triflic acid using P 4 O 10. [2] Triflic anhydride is useful for converting ketones into enol triflates. [4] In a representative application, is used to convert an imine into a NTf group. [5] It will convert phenols into a triflic ester, which enables cleavage of the C-O bond. [6] [7]

In chemistry, a reagent (/ r i ˈ eɪ dʒ ən t / ree-AY-jənt) or analytical reagent is a substance or compound added to a system to cause a chemical reaction, or test if one occurs. [1] The terms reactant and reagent are often used interchangeably, but reactant specifies a substance consumed in the course of a chemical reaction. [ 1 ]
