Outline of Final Research Achievements

To utilize carbon dioxide, we examined photocatalytic formylation of amine with carbon dioxide. Metal-loaded titanium oxide photocatalyst was found to give the aimed product from carbon dioxide and some amine compounds in acetonitrile. The reaction took place only in the acetonitrile solvent. A kinetics study revealed that the C-H bond activation of acetonitrile was an important step in the reaction mechanism. Although the product was obtained without carbon dioxide in the gas phase, the amount of the product was higher in the atmosphere of gaseous carbon dioxide. Based on these results, the following reaction mechanism was proposed: the radical species, formed from acetonitrile, reacts with the carbon dioxide, which interacts with amine, to provide the aimed product.
