Abstract
5,5-Diphenyl-2-thiohydantoin was synthesized by using benzil and thiourea as raw materials in sodium hydroxide solution.Furthermore,S-carboxyl methyl-5,5-diphenyl-2-thiohydantoin was synthesized from 5,5-diphenyl-2-thiohydantoin and sodium monochloroacetate in water.The effects of the amounts of thiourea,sodium hydroxide and water on the yields of 5,5-diphenyl-2-thiohydantoin were investigated.The effect of the amount of 5,5-diphenyl-2-thiohydantoin on the yield of S-carboxyl methyl-5,5-diphenyl-2-thiohydantoin was also studied.The optimal process route was determined.The structures of the products were characterized by IR,1H NMR,13C NMR and MS.
