The syntheses and some reactions of β, β-dichlorovinyl sulfones were investigated. The condensation of arylsulfonyl chloride with vinylidene chloride followed by dehydrochlorination with the aid of triethylamine gave the following ; β β-dichlorovinyl-phenyl sulfone (mp 4851°C), β, β-dichlorovinyl-p-tolyl sulfone (mp 5053°C), β, β-dichlorovinyl-2, 4-dimethylphenyl sulfone (mp 4548°C) and β, β-dichlorovinyl-2, 5-dimethylphenyl sulfone (mp 112115.5°C). The reaction of β, β-dichlorovinyl sulfone with aniline or with p-chloroaniline could be achieved, and the corresponding β, β-dianilinovinyl sulfone or β, β-di (p-chloroanilino) vinyl sulfone was prepared. β, β-Di (p-nitrophenoxy) vinyl sulfone was also obtained by the reaction of β, β-dichlorovinyl sulfone with sodium p-nitrophenolate, suspended in dimethyl sulfoxide.
