Wagner-Meerwein Rearrangement
Wagner-Meerwein rearrangement is an acid catalyzed conversion of an alcohol to an olefin by change in carbon skeleton through the rearrangement of the carbocation intermediate.
Mechanism of Wagner-Meerwein Rearrangement
Mechanism of Wagner-Meerwein Rearrangement takes place in two steps-
Step 1: Protonation of alcohol followed by the formation of a carbocation.
Step 2: 1,2-alkyl shift followed by loss of proton to give an alkene.
