We herein reported an electrochemical selective (deutero)hydrodefluorination reaction of trifluoroacetamides. The reaction which exhibits a remarkable chemoselectivity control and delivers (deuterium-labeled) CF2H- and CFH2-products in good yields with high level of deuterium incorporation, respectively, is enabled by the addition of different organoboron sources and (deuterated)water as the deuterium
The selectivefunctionalization of trifluoromethyl groups throughC–F cleavage poses a significant challenge due to the high bond energy of the C(sp3)–F bonds. Herein, we present dihydroacridine derivatives as photocatalysts that can functionalize the C–Fbond of trifluoromethyl groups with various alkenes undermildconditions. Mechanistic studies and DFT calculations revealed that upon irradiation
