Reactions of trifluoromethylthiocopper with halomethanes

The reaction of trifluoromethylthiocopper with halomethanes, namely di-and triiodo-, dibromodichloro-, dibromochlorofluoro-, dibromo-difluoro-, bromochlorofluoro-, phenyltrichloro-, bromocyano-and dibromofluoro-methanes, has been investigated in detail. In addition to the expected compounds, the formation of unusual products such as bis (trifluoromethyl) trithiocarbonate, dimethyl (trifluoromethylthio) benzene, bis (trifluoromethylthio) fluoromethane, (trifluoromethylthio) carbonyl fluoride, carbon disulfide, carbon tetrachloride, trifluoromethylthio-benzoate, etc. was observed. In some cases, bis (trifluoromethylthio) mercury has been used instead of trifluoromethylthiocopper. The mechanism of formation of the various products and their mass spectral fragmentation behavior are described.

Preparation of Perfluorinated Hexakis(alkylthio- and -seleno)ethanes

The perfluorinated perhetero-substituted ethanes 2a - c are prepared by irradiation of the thiocarbonates 1a - c.Upon UV-irradiation (λmax = 300 nm) bis(trifluoromethyl) trithiocarbonate (1a) decomposes by a cage process to give carbon disulfide, trifluoromethyl- and trifluoromethylthiyl radicals.In the solvent cage these radicals partly dimerize producing 3.The formation of 2a is interpreted in terms of a competition between this combination process and trapping of trifluoromethyl radicals by 1a, forming 4a, which then dimerizes.A similar mechanistic pathway is pro posed for the formation of 2b and 2c.
