We report here an efficient and highly straightforward access to α-difluoromethylated ketones through a visible light-mediated difluoromethylation of readily available enol silanes. The method, which takes advantage of the polyvalence of Hu's reagent, N-tosyl-S-difluoromethyl-S-phenylsulfoximine, used here as a CHF2 radical precursor under catalytic photoredox conditions, is practical, scalable, and provides the corresponding α-CHF2 ketones in good to excellent yields.

The mechanism of CF3 transfer from R3SiCF3 (R = Me, Et, iPr) to ketones and aldehydes, initiated by M+X- (0.004 to 10 mol %), has been investigated by analysis of kinetics (variable-ratio stopped-flo

With nitrogen too: The first catalytic [3+2] annulation of aminocyclopropanes with enol ethers is reported (see scheme; Phth=phthaloyl). The reaction worked with easily accessible phthalimidocyclopropanes using 5 mol % of SnCl4 in nearly quantitative yields. Polysubstituted cyclopentylamines, which are often present in bioactive compounds, were obtained with high diastereoselectivity and enantiospecificity. Copyright
