Difluorodiethyl ethylene dithioglycol

This reaction is very interesting in view of the unreactivity of the halogen atoms in bromofluoroethane towards many reagents. It may well be, however, that the reaction is not as simple as that represented above. 

In order to prove the identity of (XI), it was synthesized in a different manner. Ethylene dibromide was converted into ethylene dithiol, which was then heated with bromofluoroethane in the presence of sodium hydroxide. The yield by this method was small. The compound (XI), otherwise called sesqui-fluorO H , is a liquid. It is neither a vesicant nor does it produce fluoroacetate-like symptoms in the animal body. FCH,CH,Br + HSCH,CH,SH + BrCH,
