gem-Difluoroalkene is an important fluorine-containing scaffold, which has found wide application in bioactive molecules and served as a versatile building block in diverse transformations. In the past few decades, α-trifluoromethyl alkenes have stood out as powerful synthons for preparing gemdifluoroalkenes either by nucleophilic or radical-type addition/defluorination sequence, 19 and great advances have been achieved as exemplified by Zhou, 20 Molander, Wang, 22 others' groups 23 and Our group. Notably, Wang and co-workers disclosed a reductive chromium-catalyzed allylic defluorinative ketyl olefin coupling between aldehydes and α-trifluoromethyl alkenes, thereby offering efficient access to diverse gemdifluorohomoallylic alcohols (Scheme 1b). However, nearly all these studies have focused on using stoichiometric organometallic reagents and pre-activated partners, leading to limited atom and step economy. By contrast, the direct catalytic gemdifluoroallylation of unactivated Csp 3 -H bonds remains a formidable challenge, while representing a novel and original disconnection in retrosynthetic analysis for gem-difluoroalkene construction.
