An effective method is described to construct C–S/S–S bond starting from O‐alkyl phenylcarbamothioates, giving diverse O‐alkyl S‐phenyl phenylcarbonimidothioates or isothiourea disulfides, by using Cu2O as catalyst in water (without phase‐transfer catalyst) or NiBr2 catalyst at room temperature, respectively, in transformations featuring easy control, environmental friendliness, and good to excellent
描述了一种有效的方法,该方法通过使用Cu 2 O作为催化剂在水中(不使用相转移催化剂),从O-烷基苯基氨基甲硫代酸酯开始构建C-S / S-S键,得到各种O-烷基S-苯基苯基碳亚氨基硫代酸酯或异硫脲二硫化物。)或NiBr 2催化剂分别在室温下进行转化,具有易于控制,对环境友好的特点以及良好或优异的收率。
