| Outline of Final Research Achievements |
In this study, three photocatalytic reductions under hydrogen-free condition were explored. 1) Styrene was successfully hydrogenated (reduced) to ethylbenzene in alcoholic suspensions of a palladium-loaded titanium(IV) oxide (TiO2) photocatalyst, although the reduction potential of styrene is believed to be much higher than the potential of the conduction band of TiO2. 2) (2,3-Epoxypropyl)benzene was chemoselectively reduced to allylbenzene along with formation of ketones in alcoholic suspensions of a silver-loaded TiO2 photocatalyst at room temperature under atmospheric pressure, and various epoxides were also reduced to corresponding alkenes. 3) Internal alkynes were chemoselectively and diastereoselectively hydrogenated to the corresponding cis-alkenes in alcoholic suspensions of a copper-loaded TiO2 photocatalyst without the use of additives, and alkynes having functional groups such as a nitrile group were doubly-chemoselectively converted to the corresponding alkenes.
