Wagner Meerwein Rearrangement

Application for Wagner Meerwein Rearrangement ( Only demo view) :-

Mechanism :- The Wagner-Meerwein rearrangement is an organic reaction used to convert an alcohol to an olefin by the treatment an acid catalyst.

 The mechanism begins with protonation of the alcohol by the acid which is then released as water to forms a carbocation species. A 1,2-shift then occurs to form a more substituted and stabilized carbo-cation species. A final deprotonation with water produces the final olefin product and regenerates the acid catalyst.

Wagner Meerwein Rearrangement

At a glance:- 

A Wagner–Meerwein rearrangement is a class of carbocation 1,2-rearrangement reactions in which a hydrogen, alkyl or aryl group migrates from one carbon to a neighboring carbon. They can be described as cationic [1,2]-sigmatropic rearrangements, proceeding suprafacially and with stereochemical retention.

       The reaction is named after the Russian Chemist Yegor Yegorovich Vagner, he had German origin and published in German journals as Georg Wagner and Hans Meerwein.

      

        The rearrangement was first discovered in bicyclic terpenes for example the conversion of Isoborneol to camphen, which are mention on the image box and PDF file for details mechanism also.
