실험 절차

The procedure of Example 2 was followed, using 22 ml (0.17 mol) of 3-toluoyl chloride and 60 g (0.45 mol) of aluminum chloride in 120 g (0.82 mol) of 1,4-dichlorobenzene. (The molar ratio of reactants was 2.6:4.8:1.0 (AlCl3 :Dichlorobenzene:3-Toluoyl Chloride)). Pure 2,5-dichloro-3'-methyl-benzophenone was isolated in 53% yield after the crude product was recrystallized twice from hexane.
