Procedure

0.04 g of acetic acid was added to 35.98 g of isopropyl alcohol, and 4.02 g of 4-methylbenzophenone was dissolved therein. To this solution, ultraviolet rays were irradiated by a high pressure mercury lamp (UVL-100HA, manufactured by Riko Kagaku Sangyo K.K.) to carry out the reaction for 4 hours. After the reaction, the solvent was distilled off to obtain 3.99 g of 1,2-bis(p-methylphenyl)-1,2-diphenyl-1,2-ethanediol (compound (C1)).
