prepared by various synthetic methods, starting from the corresponding iodides or bromides. Methods based on sodium hydrogen sulfide, commonly used to accomplish this conversion, treatment of the Bunte salt obtained from sodium thiosulfate, the basic hydrolysis of isothiouronium salts, the hydrolysis under mild conditions of thiophosphorates formed from sodium thiophosphate and the basic hydrolysis of thiol
半氟化Ñ -alkanethiols,对称硫化物和二硫化物轴承链(一个或多个)F(CF 2)Ñ(CH 2)米与Ñ = 4,6,8,10,和米从相应的碘化物或溴化物开始,= 2、11已经通过各种合成方法制备。通常基于硫化氢钠的方法来完成这种转化,处理从硫代硫酸钠制得的邦特盐,异硫脲鎓盐的碱性水解,在温和条件下由硫代磷酸钠形成的硫代磷酸酯的水解以及硫醇乙酸的碱性水解相对于标题化合物的选择性合成,已研究并比较了其衍生物。硫代乙酸路线基本上产生带有一些二硫化物的硫醇。硫脲的结果似乎相似。硫代磷酸钠是合成硫醚的极佳途径,尤其是从溴化物开始时。基于硫化氢钠和硫代硫酸钠的两种经典方法显示出较差的选择性。有可能获得纯净状态下报告的所有硫化合物。
