A novel [2+2] cycloaddition reaction of benzenesulfonyl isocyanate is reported which canserve as a new, general method for the preparation of N-(C-amino-alkylthiomethylene) benzenesulfonamide. Benzenesulfonyl isocyanates underwent a [2+2] cycloaddition reaction with dithiocarbamates, which were obtained by treating amines with carbon disulfide and potassiumcarbonate, to give N-(C-amino-alkylthiomethylene) benzenesulfonamides in good yields.
