Tetrakis (dimethy1amino) ethylene reacts with polyhalogenated compounds either by replacing a single halogen atom with a hydrogen atom or by removing two vicinal halogens to form olefins. Hexachloroethane, lllll-trifluoropentachloropropane, and 1, 1, 1, 4, 4, 4hexafluorotetrachlorobutane react with 1 to produce the corresponding olefins by the loss of two vicinal chlorine atoms. Tetrabromoethane reacts similarly but some ...
