| Outline of Final Research Achievements |
Cross-dehydrogenative coupling of alcohols with amines to imine, imidazole, and quinoxaline over niobium oxide (Nb2O5) photocatalyst under mild conditions via in situ doping mechanism were investigated. The C-N coupling reactions of various alcohols with amines to form secondary imines take place over Nb2O5. The C-O coupling between substituted phenols and alcohols took place over Nb2O5 under visible light irradiation. Various alcohols including unstable functional group can be coupled with substituted phenols to form asymmetric ether under visible light irradiation. The correlation between photocatalytic activity and surface property of Nb2O5 was examined. The amount of surface complex is important factor for photooxidation on Nb2O5. The adsorption behavior of both substrates and products on surface of photocatalyst should be controlled to achieve a high activity.
