    Nucleophilic Trifluoromethylation of Carbonyl Compounds and Disulfides with Trifluoromethane and Silicon-Containing Bases
    摘要:
    Provided that DMF (or another N,N-dialkylformamide) is present in the reaction medium, at least in a catalytic amount, fluoroform trifluoromethylates efficiently carbonyl compounds, even enolizable ones, when opposed to (TMS)(2)N- M+, generated in situ from N(TMS)(3) and M+ F- or RO- Na+ When F- is used ina catalytic amount, silylated alpha-(trifluoromethyl)carbinols are-obtained: in this case, the four-component system HCF3/N(TMS)(3)/catalytic F-/catalytic DMF behaves like the Ruppert's reagent, especially as far as nonenolizable carbonyl compounds are concerned (CF3SiMe3 remains more efficient for enolizable carbonyl compounds). This process involves an adduct between DMF and -CF3 which is the true trifluoromethylating agent. In the same way, fluoroform efficiently trifluoromethylates disulfides and diselenides when deprotonated with a strong base selected from t-BuOK or N(SiMe3)(3)/Me4NF (or TBAT). t-BuOK is more adapted to the trifluoromethylation of aryl disulfides whereas N(SiMe3)(3)/F- is well suited to that of aliphatic disulfides.

  • Iron-Catalyzed Decarboxylation of Trifluoroacetate and Its Application to the Synthesis of Trifluoromethyl Thioethers
    作者:Benjamin Exner、Bilguun Bayarmagnai、Fan Jia、Lukas J. Goossen
    DOI:10.1002/chem.201503915
    日期:2015.11.23
    Nucleophilic CF3 has been generated by decarboxylation of potassium trifluoroacetate, arguably the most easy‐to‐handle, inexpensive, and sustainable source of trifluoromethyl groups. Simple iron(II) chloride catalyzes the decarboxylation as well as a subsequent trifluoromethylation of organothiocyanates, resulting in a straightforward synthesis of trifluoromethyl thioethers. The KCN byproduct is absorbed by
    亲核CF 3是由三氟乙酸钾脱羧生成的,而三氟乙酸钾可以说是最易于处理,廉价且可持续的三氟甲基来源。简单的氯化铁(II)催化有机硫氰酸酯的脱羧以及随后的三氟甲基化,从而直接合成三氟甲基硫醚。KCN副产物被铁(II)吸收,形成了无毒的六氰合铁酸钾。醛与三氟乙酸酯的类似三氟甲基化反应强调了这种铁催化的脱羧三氟甲基化反应的合成潜力。

    alkylation reaction was effective without the use of UV irradiation with all but three substrates (thiosalicylic acid, 1k; 2-mercaptobenzimidazole, 1q; and 3-mercaptopropionic acid, 1r). Steam-distillation was found as an effective and easy to upscale means for the isolation of these volatile and water immiscible sulfides. The CF3I reagent gas was conveniently weighed and delivered to the reaction mixture
