The reaction of 3,3-bis(trifluoromethyl)-5-alkoxy-1,2-dithiolanes (RO= OEt or OBu-n) proceeds through thiophilic attack of BuLi leading to the formation of ring-opened product BuSCH(OR)CH₂C(CF₃)₂SLi, which can be converted into the corresponding thiols or sulfides by the reaction with H⁺ or alkyl halide. Interaction of 3,3-bis(trifluoromethyl)-5-n-butoxy-1,2-dithiolane with CF₃Si(CH₃)₃ resulted in unusual reaction leading to the formation of CF₃SCH(OBu)CH₂C(CF₃)=CF₂ (7). The treatment of 7 with CsF in the presence pentafluoropyridine led to equimolar mixture of 2-n-butoxy-1,1-bis(trifluoromethyl)cyclopropane and 4-(trifluoromethylthio)tetrafluoropyridine (as a result of interception of liberated in this process CF₃S- anion by pentafluoropyridine).

3,3-双（三氟甲基）-5-烷氧基-1,2-二硫杂环戊烷（RO = OEt或OBu-n）的反应通过BuLi的亲硫性攻击进行，导致开环产物BuSCH（OR）CH的形成₂ C（CF ₃）₂ SLi，可通过与H ⁺或烷基卤化物反应转化为相应的硫醇或硫化物。3,3-双（三氟甲基）-5-正丁氧基-1,2-二硫杂环戊烷与CF ₃ Si（CH ₃）_3的相互作用导致异常反应，导致CF ₃ SCH（OBu）CH ₂ C（ CF ₃）= CF ₂（7）。治疗7在存在五氟吡啶的条件下用CsF生成2-正丁氧基-1,1-双（三氟甲基）环丙烷和4-（三氟甲硫基）四氟吡啶的等摩尔混合物（由于在此过程中截获了游离的CF ₃ S-阴离子五氟吡啶）。
