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.
