Critical control by temperature and pressure of enantiodifferentiating anti-markovnikov photoaddition of methanol to diphenylpropene in near critical and supercritical carbon dioxide
The enantiomeric excess of photoadduct obtained in the title reaction was critically manipulated not only by pressure (P) but also by temperature (T), exhibiting substantially different P-dependence profiles at different T, yet sharing a sudden leap near the critical density at each T, for which the difference in clustering property of methanol in near and supercritical CO2 is thought to be responsible.
