Herein, we report an indirect trifluoromethylthiolation of sodium arylsulfinates. This transition-metal-free reaction significantly provides an environmentally friendly and practical synthetic method for aryl trifluoromethyl thioethers using commercial Ruppert–Prakash reagent TMSCF3. This approach is also a potential alternative to the current industrial production method owing to facile substrates

universal and efficient Cu(I)-catalyzed synthesis of aryl and alkyl trifluoromethyl sulfides has been developed. In this catalytic system, S-aryl or S-alkyl sulfothioate (I or II) proved to be the key intermediate. Substrates bearing groups of I, Br, Cl, OTs, and OMs on the aryl carbon and no matter electron-withdrawing and electron-donating substitutions on the aromatic ring could afford good to excellent
A series of copper(I) trifluoromethyl thiolate complexes have been synthesized from the reaction of CuF2 with Me3SiCF3 and S8 (see scheme; Cu red, F green, N blue, S yellow). These air‐stable complexes serve as reagents for the efficient conversion of a wide range of aryl halides into the corresponding aryl trifluoromethyl thioethers in excellent yields.
2,4-Diamino-6-phenyl-s-triazine derivatives which are substituted in the 3-position of the phenyl ring and optionally further substituted in the 6-position demonstrate anti-ulcer and diuretic properties. A representative embodiment is 2,4-diamino-6-(3-trifluoromethylthiophenyl)-s-triazine.
