Phenylvinylsulfone derivatives were synthesized by Kirners condition. The structure of these compounds were ascertained by means of ultraviolet, melting point, IR and ^1H-NMR spectra. The nucleophilic addtion reaction kinetics of L-cysteiene for phenylvinylsulfone was investigated by ultraviolet spectrophotlmetery in 40% EtOH-H_2O at 25℃. The rate equations which were applied over a wide pH 1.0~13.0 range. On the basis of general base catalysis and confirmation of addtion reaction product, the nucleophilic addtion reaction kinetics of L-cysteiene for phenylvinylsulfone were measured by the pH change. From the result of the above caption, a plausible nucleophilic addtion reaction mechanism of L-cysteiene for phenylvinylsulfone was proposed. These compounds may by used ad the starting materials for the preparation of the engineering plastics or the germicide.
