Pinacol rearrangement reaction is 1,2-diol in acid-catalyzed intramolecular rearrangement dehydration, the formation of pinacolone reaction. Pinacolone is an important organic chemical intermediates, widely used in pesticides, medicine, dyes and other fields. This review summarizes the recent advances in the rearrangement of pinacol, including the rearrangement of pinacol in liquid water and supercritical water at high temperature, the catalysis of inorganic acids, Lewis acids and molecular sieves, the reaction under solid phase conditions, and Photochemical, electrochemical rearrangement and other aspects of research.
