Direct substitution and elimination reactions of the fluorine atoms of difluoromethylene CF2α groups of nonspaced perfluoroalkyl chains, CF3 groups are very difficult to achieve. But, they become feasible with fluoro-alkenes, alkynes, imines or carbonyl derivatives, for which vinylic substitution and related carbanion-mediated pathways are available. In this review, we classify the major and unique flu-orine substitution/elimination and rearrangement reactions and discuss their contribution to the synthe-sis of heterocyclic compounds.
Fluorine elimination/substitution, perfluoroalkyl chain, trifluoromethyl, vinylic fluorine, allylic fluorine, organofluorinated compounds.
