The simple 2-fluorotosylates eliminate p-toluenesulphonic acid (HOTs) in basic media, the tosyl group being substituted by the action of a nucleophile. In contrast the F- alkylated homologous RFCHOTsCH2F undergo elimination of HF in the presence of a donor reagent leading to the 1-F-alkylvinyl p-toluenesulphonates RFCOTsCH2. Depending on the reaction conditions and the nature of the base, these
