trans-Chlorotetrafluoro(trifluoromethyl)sulfur(VI), CF3SF4Cl, readily undergoes reductive defluorination to sulfur(IV)-containing compounds when it is reacted with nitrogen- or oxygen-containing nucleophiles. Thus, CF3S(NR2)2Cl results from a variety of nitrogen bases, such as R2NH = piperidine, 2,6-dimethylpiperidine, 2,2,6,6-tetramethylpiperidine, morpholine, 3,5-dimethylmorpholine, and N,N'-dimethylethenediamine
当反式四氟四氟(三氟甲基)硫(VI)CF 3 SF 4 Cl与含氮或氧的亲核试剂反应时,很容易发生还原脱氟化为含硫(IV)的化合物。因此,CF 3 S(NR 2)2 Cl源自多种氮碱,例如R 2 NH =哌啶,2,6-二甲基哌啶,2,2,6,6-四甲基哌啶,吗啉,3,5-二甲基吗啉,和N,N'-二甲基乙二胺。与醇一起形成CF 3 S(OR f)2 Cl,其中R fOH = 2,2,2-三氟乙醇和1,1,1-三氟-2-丙醇。由于所有这些化合物的稳定性均很低,因此很难完全表征。
