Procedimiento

A mixture of biphenyl (10 g, 0.065 mol) and 4-chlorobenzenesulphonyl chloride (13.69 g, 0.065 mol) in trichlorobenzene (3 mL) was heated with stirring to 110° C. Anhydrous ferric chloride (0.05 g, 0.0003 mmol) was added and stirring was continued at 150° C. for 16 h. The cooled solid was stirred with methanol (200 mL). The product was filtered, washed with methanol, dried, and recrystallised from acetic acid to give 4-(4′-chlorobenzenesulphonyl)biphenyl (13.9 g, 65%); m.p. 169° C. (lit. 171-173° C.).
