Carboxylation of Naphalene -Photofixation of Carbon Dioxide by Radical Anion-

Abstract Reductive photocarboxylation of naphthalene on a UV irradiation was investigated using amines, indene, and dimethoxybenzenes as reducing agents. 1- and 2-naphthoic acids and dihydronaphthalene carboxylic acid were obtained. The quantum yield of the reaction depended on a donor and solvent, however, the yield scarcely correlated with oxidation potential of a donor. Furthermore, naphthalene was reduced by using a sensitizer even on a visible light irradiation
