A modular synthetic method, involving a hydrothiolation, silylation, and fluoroalkylation, for the construction of highly functionalized fluoroalkyl sulfides has been developed. The use of aprotic polar solvents enables the additive-free chemoselective hydrothiolation of tetrafluoroethylene, trifluorochloroethylene, and hexafluoropropene with various thiols. The stepwise functionalization reactions
已经开发出一种模块化的合成方法,该方法涉及加氢硫基化,甲硅烷基化和氟代烷基化,用于构建高度官能化的氟代烷基硫化物。非质子极性溶剂的使用使得四氟乙烯,三氟氯乙烯和六氟丙烯与各种硫醇的无添加剂化学选择性氢硫醇化成为可能。逐步官能化反应可高效地将氢硫醇化的中间体转化为四氟乙基硫化物。该方法避免了使用环境污染物Halon-2402,该污染物在已报道的合成路线中用作构件。
