Synthesis of bis(trifluoromethyl)trisulfide and bis(trifluoromethylthio)selenide

The use of 4-dimethylaminopyridine as a catalyst in the reaction of trifluoromethylsulfenyl chloride with hydrogen sulfide at -78 deg C cuts down the time of reaction from 30 d to 1 d and gives up to 70percent yield of bis(trifluoromethyl)trisulfide (1).Similarly, bis(trifluoromethylthio)selenide (2) can be prepared from hydrogen selenide and trifluoromethylsulfenyl chloride.The influence of other catalysts on the course of the reaction, the formation of unusual by-products, the NMR and mass spectral data of 1 and 2 are presented in this paper.

Simultaneous scission of C-S and S-S bonds of bis(trifluoromethyl)trisulfide by Grignard reagents

Trifluoromethyl mono-, di- and tri-sulfides, and alkyl sulfides and disulfides, as well as dimerized products, are formed as a result of the simultaneous cleavage of the C-S and S-S bonds of bis(trifluoromethyl)trisulfide by Grignard reagents at -78 deg C.The formation of various products has been rationalized on the basis of the involvement of free radicals.
