the synthesis of thiocarbamates has been developed. When dialkyl or diaryl disulfides were allowed to react with secondary amines and carbon monoxide in the presence of a catalytic amount of a palladium complex, the thiocarbamates were obtained in moderate to good yields. In contrast to that of secondary amines, in the reaction of a primary amine, no formation of thiocarbamate was confirmed, but urea
已经开发了合成硫代氨基甲酸酯的新方法。当在催化量的钯配合物存在下使二烷基或二芳基二硫化物与仲胺和一氧化碳反应时,以中等至良好的产率获得了硫代氨基甲酸酯。与仲胺相反,在伯胺的反应中,未确认到硫代氨基甲酸酯的形成,但是以高收率形成了尿素。
