A general and convenient copper-mediated trifluoromethylthiolation of primary and secondary alkyl halides was described. Variation of the solvent, additives and time allowed optimization of the reaction. A wide range of alkyl halides were explored to give a set of alkyl trifluoromethyl thioethers in moderate to excellent yields. A variety of functional groups, including ethers, thioether, esters, nitriles, amides, and ketal groups, were well tolerated in the electrophilic partner.

Ionic Liquids for Fast and Solvent-Free Nucleophilic Trifluoromethylthiolation of Alkyl Halides and Alcohols
The trifluoromethylthiogroup is of rising interest in medicinal, agrochemical, and materials chemistry. Although several strategies for the introduction of this functional group have been described, new synthetic methods are needed. A novel ionic liquid, 1-n-butyl-3-methylimidazolium trifluoromethylthiolate, has been developed and is herein reported as an efficient and recyclable in situ generated

It's so easy! Direct trifluoromethanesulfanylation reactions remain difficult to perform because of the lack of reagents that are stable and easy to handle. Trifluoromethanesulfanamides are reagents which, in combination with readily available Grignard reagents, can be used by those without experience in fluorine chemistry to easily synthesize trifluoromethylthioethers.

Te-trifluoromethylated dibenzoheterocyclic onium salts, their derivatives, and related salts were synthesized by the direct fluorination of a mixture of 2-[(trifluoromethyl)thio- or seleno]biphenyls and triflic acid (TfOH) or HBF 4 etherate, by treatment of the corresponding sulfoxides and selenoxides with Tf 2 O by a new type of tellurium activation of 2-[(trifluoromethyl)telluro]biphenyls with Tf 2 O and (CH
S-、Se-和 Te-三氟甲基化二苯并杂环鎓盐、它们的衍生物和相关盐是通过 2-[(三氟甲基)硫代或硒代]联苯和三氟甲磺酸 (TfOH) 或 HBF 的混合物的直接氟化合成的4 醚化物,通过使用 Tf 2 O 和 (CH 3 ) 2 SO 对 2-[(三氟甲基) 碲] 联苯进行新型碲活化,或通过鎓的衍生,用 Tf 2 O 处理相应的亚砜和硒氧化物得到的盐。反应性检查表明,与非杂环盐相比,三氟甲基杂环盐具有很强的反应性,并表明该杂环盐体系可作为广泛适用的三氟甲基化剂的来源
