Selective C-F bond activation of the trifluoromethyl group is an important approach for the synthesis of gem-difluoro compounds. Given the importance of trifluoromethyl alkenes in synthetic chemistry as well as their diversity in selectivity, the research on selective C-F bond activation of these compounds has received considerable interest. To this end, The research progress is summarized, including nucleophilic addition/defluorination (SN2' type), acid-promoted defluorinative Friedel-Crafts arylation, (formal) ipso-defluorinative functionalization, and transition-metal-catalyzed migratory insertion/ defluorination.
