PRESENTATION TOPIC:

REDUCTION OF

PINACOL

REDUCTION OF PINACOLS: It is a bimolecular reduction reaction ketones+magnesium amalgam(Mg-Hg)

+water=Pinacols

PINACOL REARRANGEMENT Pinacol Rearrangement is also called

as Pinacol-Pinacolone rearrangement. It is an acid catalyzed organic chemical

reaction in which 1, 2-diols are converted to carbonyl compounds.

The name comes from the reactant and the product that is pinacol to pinacolone. This reaction is named after a German chemist Wilhelm Rudolph Fittig in 1860.

For example, consider the following reaction:
