This mixture (17 g, 0.05 molar as 1-chloro-2-phenyl-2-propene) is dissolved in DMF (100 cc). Sodium benzenesulphinate (8.2 g, 0.05 mole) is added and the mixture is heated to 70° C. for 2 h. The reaction mixture is poured into water and ice (350 g). It is stirred energetically with pentane (150 cc) to extract the 1-chloro-2-phenyl-1-propene and the 1-chloro-2-phenyl-2-propanol which have not reacted, for 15 to 30 min until crystallization is complete. The crystals formed are filtered off, are washed with pentane (50 cc) and with diisopropyl ether (50 cc) and are thoroughly drained and dried. 2-Phenyl-1-phenylsulphonyl-2-propene (9.8 g, 76%) is obtained. Mp=105° C.
