REACTIONS OF TRIFLUOROMETHYLTHIOCOPPER WITH HALOMETHANES

The reaction of trifluoromethylthiocopper with halomethanes, namely di - and triiodo-, dibromodichloro-, dibromochlorofluoro-, dibromodifluor o-, bromochlorofluoro-, phenyltrichloro-, bromocyano- and dibromofluor o-methanes, has been investigated in detail. In addition to the expect ed compounds, the formation of unusual products such as bis(trifluorom ethyl) trithiocarbonate, dimethyl(trifluoromethylthio)benzene, bis(tri fluoromethylthio) fluoromethane, (trifluoromethylthio) carbonyl fluori de, carbon disulfide, carbon tetrachloride, trifluoromethylthiobenzoat e, etc. was observed. In some cases, bis(trifluoromethylthio)mercury h as been used instead of trifluoromethylthiocopper. The mechanism of fo rmation of the various products and their mass spectral fragmentation behavior are described.
