2-trifluoroethane (Halothane®) and various aliphatic and aromatic thiols in the presence of sodium dithionite/sodium bicarbonate is described. The synthetic utility of the prepared sulfides is illustrated by the synthesis of biologically potent heterocycles and by their electrophilic reactions with thiophene. thiols - radical reactions - alkylations - fluorinated compounds - sulfides

A convenient one step synthesis of chlorotrifluoroalkyl olefins starting from aldehydes was developed. The stable reagent 2-((1-chloro-2,2,2-trifluoroethyl)sulfonyl)benzothiazole was prepared from readily available benzothiazole-2-thiol and halothane. This method comprises using stable 2-((1-chloro-2,2,2-trifluoroethyl)sulfonyl)benzothiazole according to the Julia procedure and presents new opportunities
开发了一种从醛开始的方便的一步合成氯代三氟烷基烯烃。由容易获得的苯并噻唑-2-硫醇和氟烷制备稳定的试剂 2-((1-氯-2,2,2-三氟乙基)磺酰基)苯并噻唑。该方法包括根据 Julia 程序使用稳定的 2-((1-氯-2,2,2-三氟乙基)磺酰基)苯并噻唑,并为合成三氟亚烷基衍生物提供了新的机会。
