| Outline of Final Research Achievements |
A binaphthyl-based secondary amine catalyst having hydroxy group as a bifunctional organocatalyst was synthesized and applied to the reaction between aliphatic aldehyde and nitrosobenzene. 2-Naphthol is a weak organic acid and its acidity is known to be increased by UV irradiation. The newly synthesized bifunctional catalyst, which has 2-naphthol moiety, was found to promote both aminoxylation and hydroxyamination. Under UV irradiation, the product ratio of aminoxylation and hydroxyamination changed. This result suggested that the acidity of the bifunctional catalyst was increased by UV irradiation, since the aminoxylation requires a relatively strong acid catalyst.
