A mixture liquid of 3.16 g (39.5 mmol) of 1,3-cyclohexadiene, 10.5 g (34.1 mmol) of trans-1,2-bis(phenylsulfonyl)ethylene and 200 ml of toluene was refluxed for 7 hours, then cooled and concentrated under reduced pressure to give a reaction mixture. This crude reaction product was recrystallized from chloroform/hexane, giving 5,6-bis(phenylsulfonyl)-bicyclo[2.2.2]octa-2-ene (13.8 g, 35.6 mmol, yield 90%).
