三氟甲硫醇是一種有機硫化合物，化學式為CF₃SH，它是一種硫醇。它最早於1953年被製得。^[4]^[2]

製備

三氟甲硫醇最初由三氟甲硫醇汞和氯化氫氣體的反應製得；後來，人們又發現了硫代碳醯氟和氟化氫氣體的反應可以產生三氟甲硫醇。其它方法還有三氟甲基二硫化物和硫化氫在紫外光下的反應：^[4]

CF₃SSCF₃ + H₂S → 2 CF₃SH + S

以及一些三氟甲硫基的一些衍生物的反應：^[5]

CF₃SBr + HBr → CF₃SH + Br₂

3 CF₃SNCO + 6 HI → 3 CF₃SH + 3 I₂ + (HNCO)₃

性質

三氟甲硫醇可以和烯烴或炔烴發生加成反應，如和CF₂=CFCl^[6]、CH₂=CHCl^[7]等物質的反應：

它和N-碘代丁二醯亞胺（NIS）反應，可以得到碘代產物CF₃SI。^[8]
