Trimethyl-2-fluoroethyl ammonium

Advantage was taken of the fact that of the two halogens in fluorobromoethane, FCHaCH2Br, the bromine atom is the more reactive. When, for example, trimethylamine and fluorobromoethane were allowed to react at room temperature, addition took place and 2-fluoroethyl trimethyl ammonium bromide was... 

The study of these fluorine-containing salts was then extended, and we prepared other new compounds in this series, e.g. 2-fluoroethyl glycine hydrochloride and 2-fluoroethyl betaine hydrochloride (that is, carbofluoroethoxy-methyl trimethyl ammonium chloride). The first of these was readily prepared by the Fischer-Speier esterification of glycine with fluoro-ethyl alcohol ...
