The use of 4-dimethylaminopyridine as a catalyst in the reaction of trifluoromethylsulfenyl chloride with hydrogen sulfide at −78 °C cuts down the time of reaction from 30 d to 1 d and gives up to 70% yield of bis(trifluoromethyl)trisulfide (1). Similarly, bis(trifluoromethylthio)selenide (2) can be prepared from hydrogen selenide and trifluoromethylsulfenyl chloride. The influence of other catalysts
在-78°C下,在三氟甲基亚硫酰氯与硫化氢的反应中使用4-二甲基氨基吡啶作为催化剂,可将反应时间从30 d缩短至1 d,并获得高达70%的双(三氟甲基)三硫化物收率(1)。类似地,双(三氟甲硫基)硒化物(2)可由硒化氢和三氟甲基亚硫酰氯制备。本文介绍了其他催化剂对反应过程的影响,异常副产物的形成,1和2的NMR和质谱数据。
