An electroreductive access to gem-difluoroalkenes has been developed through the decarboxylative/defluorinative coupling of N-hydroxyphtalimides esters and α-trifluoromethyl alkenes. The electrolysis is performed under very simple reaction conditions in a

Herein, we report a method that combines hydrogen atom transfer and photoredox catalysis to achieve the dehydrogenative difluoroallylation of amides, ethers, and alkyl aldehydes. This operationally convenient method transforms a broad scope of substrates into the corresponding gem-difluoroalkenes via the construction of C(sp3)-C(sp3) or C(sp3)-C(sp2) bonds. Excellent functional group compatibility and high selectivity make this method have a wide range of substrate types and render it suitable for late-stage modification of pharmaceutical intermediates.

A site-selective defluorinative sp3 C-H alkylation of secondary amides that rapidly and reliably incorporates gem-difluoroalkene motifs into previously unfunctionalized sp3 sites is disclosed. This protocol is distinguished by its mild conditions, wide scope, and exquisite site-selectivity, thus unlocking a new platform to introduce carbonyl isosteres at saturated hydrocarbon sites.
