What is the function of Claisen adapter?
The Claisen adaptor is a multi-purpose item of standard taper glassware. It is used in situations which require more than one outlet from a round-bottom flask. For instance, in a reflux of a reaction mixture, sometimes it is necessary to condense the rising vapors and add reactants to the mixture at the same time.
What type of reaction is Claisen?
The Claisen condensation reaction is an organic coupling reaction that results in the formation of a C-C bond between either a single ester and one carbonyl compound or between two esters. The reaction proceeds when a strong base is present and the product of the reaction is a beta-keto ester or a beta-diketone.
Why is Claisen condensation important?
The Claisen condensation – strictly the condensation of two esters with the concomitant release of one of the constituent alcohol moieties – is arguably the most important carbon–carbon bond-forming reaction in biology, as it is used in the biosynthesis of fatty acids, polyketides, and a large variety of other
