A procedure has been developed for the synthesis of 1,1,1-trichloro-2-sulfanylpropan-2-ol and 1,1,3-tribromo-2-sulfanylpropan-2-ol via acid-catalyzed addition of hydrogen sulfide to the corresponding ketones. The stability of the resulting hydroxy thiols was estimated by analyzing the potential energy surface for the reaction of 1,1,1-trichloropropan-2-one with hydrogen sulfide in the presence of hydrogen chloride. In addition, quantum-chemical analysis of rotational isomerism of 1,1,1-trichloro-2-sulfanylpropan-2-ol was performed.
通过硫化氢与相应酮体的酸催化加成,开发了一种合成 1,1,1-三氯-2-硫代丙烷-2-醇和 1,1,3-三溴-2-硫代丙烷-2-醇的程序。通过分析 1,1,1-三氯丙-2-酮在氯化氢存在下与硫化氢反应的势能面,估计了所生成的羟基硫醇的稳定性。此外,还对 1,1,1-三氯-2-硫基丙-2-醇的旋转异构进行了量子化学分析。
