  • Thiophilic ring opening reactions of 3,3-bis(trifluoromethyl)-5-alkoxy-1,2-dithiolanes under action of nucleophiles
    作者:Viacheslav Petrov
    DOI:10.1016/j.jfluchem.2018.05.004
    日期:2018.8
    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
    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)。

    日期:——
    A synthesis of the stable ionic trifluoromethanethiolate salts, TDAE2+2SCF3− (1) and TDAE2+SCF3−Cl− (2) was accomplished in quantitative yields via reduction of bis(trifluoromethyl) disulfide and trifluoromethanesulfenyl chloride using tetrakis(dimethylamino) ethylene (TDAE). The salts were found to be stable up to their melting points. The trifluoromethanethiolate salt [TDAE2+2SCF3− (1)] was for the

  • Trifluoromethylthiolation of aromatic substrates using thiophosgene—fluoride salt reagents, and formation of byproducts with multi-carbon chains
    作者:Stewart J. Tavener、Dave J. Adams、James H. Clark
    DOI:10.1016/s0022-1139(99)00063-9
    日期:1999.6
    Reaction of potassium fluoride or tetramethylammonium fluoride with thiophosgene leads to the formation of a nucleophilic source of trifluoromethanethiolate, suitable for the preparation of trifluoromethyl aryl sulfides from activated haloaromatics. Analysis of the byproducts in the system demonstrates that complex molecules with up to C-4 chains may be formed by the reaction of fluoride salts with thiophosgene. (C) 1999 Elsevier Science S.A.

  • A new synthesis of trifluoromethanethiolates—characterization and properties of tetramethylammonium, cesium and di(benzo-15-crown-5)cesium trifluoromethanethiolates
    作者:Wieland Tyrra、Dieter Naumann、Berthold Hoge、Yurii L. Yagupolskii
    DOI:10.1016/s0022-1139(02)00276-2
    日期:2003.1
    [NMe4]SCF3, CsSCF3 and [(B-15-C-5)(2)Cs]SCF3 (B-15-C-5: benzo-15-crown-5) are formed from reactions of the corresponding fluorides, trimethyl(trifluoromethyl)silane, Me3SiCF3, and elemental sulfur in glyme or THF. All compounds are colorless to pale ochre solids decomposing significantly above ambient temperature. Excellent agreement between experimental and theoretical vibrational frequencies, calculated at the B3PW91 level of theory, impressively confirms the salt-like nature of [NMe4]SCF3. The properties of the title compounds as nucleophilic SCF3 transfer reagents were checked with a variety of organic, organometallic and inorganic compounds. (C) 2002 Elsevier Science B.V.
