An efficient method is disclosed for the synthesis of novel α,β-unsaturated sulfonic
acid derivatives containing dithiocarbamate/xanthate groups through ring opening of
an α,β-unsaturated γ-sultone with dithiocarbamic acid salts or xanthates prepared
in situ. Treatment of the primary products with hydrochloric acid afforded the corresponding
β-chloro-γ-(dithiocarbamato)propanesulfonic acids in excellent yields.
Key words
dithiocarbamates - sultones - xanthates - sulfonic acids - nucleophilic substitution
- propene sultone
