✦ Synopsis

Condensation of 1,1,2-trichlorotrifluoroethane with potassium thiophenoxide occurs in DMF or DMSO to give aryl-2,2dichloro-1,1,2-trifluoroethylsulfides :

The same condensation with phenoxide gives two products :

The formation of aryl-2,2-dichloro-1,1,2-trifluoroethylsulfides or ethers can be explained by a chain carbanionic mechanism.
