Photoredox-catalyzed silyldifluoromethylation of silyl enol ethers (Beilstein Journal of Organic Chemistry)
 


Abstract A method for the light-mediated fluoroalkylation of silyl enol ethers with (bromodifluoromethyl)trimethylsilane followed by a reduction of the primary products with sodium borohydride is described. An 18 W, 375 nm LED was used as the light source. The reaction is performed in the presence of a gold photocatalyst, which effects the generation of a (trimethylsilyl)difluoromethyl radical via cleavage of the carbon–bromine bond. Beilstein J. Org. Chem. 2020, 16, 1550–1553. doi:10.3762/bjoc.16.126
