This mixture (17 g, 0.05 moles as 1-chloro-2-phenyl-2-propene) is dissolved in dimethylformamide (100 cc). Sodium benzenesulphinate (8.2 g, 0.05 moles) is added and the mixture is heated to 70° C. for 2 h. The reaction mixture is poured into ice and water (350 g). It is stirred vigorously with pentane (150 cc) to extract the unreacted 1-chloro-2-phenyl-1-propene and 1-chloro-2-phenyl-2-propanol for 15 to 30 min until crystallization is complete. The crystals formed are filtered off, are washed with pentane (50 cc) and diisopropyl ether (50 cc), are drained thoroughly and are dried. 2-Phenyl-1-phenylsulphonyl-2-propene (9.8 g, 76%) is obtained. Mp=105° C.
