Abstract
Visible light-induced photocatalytic fixation of CO2 into benzophenone (1) has been carried out in CO2-saturated DMF (N, N-dimethylformamide) using poly (p-phenylene)(PPP) as a heterogeneous photocatalyst and triethylamine as an electron donor. Diphenylglycolic acid (2) is produced as a CO2-fixed product together with benzhydrol (3), benzopinacol (4) and 1, 1-diphenylpropane-1, 2-diol (5). The presence of quaternary onium salts such as ...
