Abstract
This invention is intended to provide a method for producing pinacoline by means of pinacol rearrangement in supercritical water, which affords an extremely high reaction rate without the addition of high concentrations of acid, and this invention is directed to a method for increasing the reaction rate during organic synthesis by utilizing the supply of protons from water under noncatalytic conditions in supercritical water, a method of pinacol rearrangement comprising the production of pinacoline by pinacol rearrangement under noncatalytic conditions without the addition of an acid catalyst in supercritical water, and a method of synthesis comprising the production of cyclic compounds from pinacol under noncatalytic conditions without the addition of an acid catalyst around the critical point (375 to 380° C., 22.5 to 25 MPa) in supercritical water.
