| Outline of Final Research Achievements |
A conversion of stoichiometric reaction into catalytic reaction is of significant in molecular transformations. It is known that stoichiometric amounts of silver can promote decarbonyl amination of benzoxazole through C-H activation. In this research, decarbonyl amination of benzoxazole using silver nanoparticles was investigated under light irradiation. Metal oxides-supported O valent silver nanoparticles did not proceed the decarbonyl amination. In contrast, metal oxide-supported silver ion promoted the reaction. However, leaching of silver ion from metal oxide occurred and catalytic cycle involving reduction of silver ion to silver nanoparticles following by re-oxidation of silver nanoparticles to silver ion by the light irradiation did not take place.
