実験手順
A mixture of 2-bromo-2-(p-chlorophenyl)-4-phenylindane-1,3-dione (0.3 g), silver nitrate (0.15 g) ethanol (3 ml) and water (3 ml) was heated under reflux for 2 hours. After cooling, the precipitated solid was filtered off. The solvent was removed from the filtrate under reduced pressure and the residual solid was chromatographed in silica. Recrystallisation from ethanol-water of the fraction eluted with ethyl acetate afforded 2-(p-chlorophenyl)-2-hydroxy-4-phenylindane-1,3-dione, m.p. 161-163.
