- Synthetic method of aryltrifluoromethyl sulfide
-
The invention provides a synthesis method of an aryltrifluoromethyl sulfide compound, which comprises the following steps: mixing aryl halide, silver trifluoromethane mercaptide, a copper salt catalyst, a nitrogen-containing organic ligand and an organic solvent, and stirring at 20-120 DEG C to react for 1-60 hours, so that after the reaction is finished, the aryl trifluoromethyl thioether compound is generated. The method has the advantages of cheap and easily available raw materials, mild reaction conditions, good substrate universality, high yield, suitability for industrial application and the like.

- Electrochemical Trifluoromethylation of Thiophenols with Sodium Trifluoromethanesulfinate
-
We developed an electrochemical trifluoromethylation of thiophenols without the use of metal catalysts and oxidants. This reaction features mild reaction conditions, readily available substrate, as well as moderate to good yields. In addition, this protocol can be easily scaled up with moderate efficiency.

- Novel reactions of perfluoroalkylphenyl sulfides with organolithium reagents
-
The reaction of anisole with organolithium reagents, commonly known as ortho-directed metallation, is of considerable synthetic utility in organic chemistry and as such has attracted considerable attention in recent years.Over the past 50 years, several mechanisms have been proposed to account for the observed regioselective metallation.For the first time, the reaction of perfluoroalkylphenyl sulfides with organolithium reagents has been investigated and found to furnish products resulting from the replacement of the perfluoroalkyl moieties with alkyl groups derived from the metallating agents.Phenyltrifluoromethyl ether, the anisole analog, failed to undergo metallation.A rationalization for the formation of unusual products via mediation of a single-electron-transfer process is presented in this paper together with the spectral data of the products. - Keywords: Reactions; Perfluoroalkylphenyl sulfides; Organolithium reagents; NMR spectroscopy; Mass spectrometry; Orthometallation
