| Outline of Final Research Achievements |
The catalytic radical reactions were developed by the use of photocatalysts having the potential to induce the oxidation or reduction. (1) The catalytic and chemoselective oxidation of cinnamaldehyde derivatives was achieved by using rhodamine 6G as an organophotocatalyst. The catalysis using rhodamine 6G promoted the oxidation of olefin moiety in a chemoselective manner. In contrast, the cooperation between rhodamine 6G and N-heterocyclic carbene (NHC) allowed the oxidative esterification of formyl group. (2) The chiral TiO2 catalysts were developed for the asymmetric reduction of aromatic ketones. When a chiral mandelic acid-adsorbed TiO2 catalyst was used, the alcohols were obtained with a reasonable enantioselectivities. (3) When charge-transfer complex between iodine and amines was employed, the radical addition reactions proceeded under visible light irradiation in the absence of the typical photocatalysts.
