Beckmann Rearrangement
“The acid-induced reaction that converts oxime to amide is called Beckmann rearrangement” In the Beckmann rearrangement, migration of the group does not depend upon migration aptitude but depends upon the orientation of the group related to a hydroxyl group. In…
Pinacole-pinacolone rearrangement
An Acid catalyzed rearrangement in which 1,2-diol or pinacole is converted to carbonyl compound is called pinacole- pinacolone rearrangement. Pinacole : 2,3- dimethyl butane-2,3-diol Pinacolone :3,3-dimethyl-2- butanone Reaction of Pinacole-pinacolone rearrangement: Mechanism of pinacole-pinacolone rearrangement: Mechanism of pinacole-pinacolone rearrangement takes place in four steps Step(01): In this step hydroxyl group of pinacole is protonated by…
Favorskii Rearrangement
Base catalyzed rearrangement in which α-halo ketone or cyclopropane having at least one α-H reacts with base give carboxylic acid or their derivatives. In favorskii rearrangement, the base decides our product e.g. if alkoxide is used as a base then an ester will be formed. If hydroxide is used as a base then carboxylic acid…
