Reaction Conditions

Reaction Steps

(β-chloroethylsulfonyl)benzene (40.9 g, 200 mmol) was dissolved in 100 g of toluene, to this solution were added 30.7 g of 49% aqueous potassium carbonate solution (potassium carbonate 109 mmol) and 1.01 g (10 mmol) of triethylamine, and the mixture was stirred for 3 hours at from 40 to 45° C. Then, the mixture was washed with 70 g of water once, with 35 g of 5% aqueous sulfuric acid solution once and further with 35 g of water once, and the solvents were distilled off to obtain 33.1 g (yield 98.4%) of phenylvinylsulfone.
