Preliminary kinetics of the Diels –Alder (DA) couplings of N-ethylmaleimide with 9-anthracenemethanol in high temperature water (T > 100 °C and P > 200 bar) will be presented. We are investigating the effect of changing the physical properties of high temperature water (HTW), by manipulating the temperature and pressure, to understand the underlying physical chemistry of the Diels-Alder reaction. Reactions in HTW provides a rational means for investigating the hydrophobic and H-bonding contributions to the aqueous acceleration of Diels-Alder reactions due to changes in the dielectric constant and H-bonding with temperature and pressure.
