that perturbation of the electronic character of the ketone can further encourage the formation of the hydrate. The more facile conversion betweenketone and hydrate forms suggests that analogues should readily covalently inhibit proteases and other enzymes. Further functionalization of the ketone group enables access to other useful fluorinated functional groups.

prepared by the reaction of a gem-difluorinated alkene with a P–H bond, though such nucleophilic reactions instead proceed through a C–F substitution pathway that delivers monofluorovinyl products. In contrast, we report a peroxide-initiated hydrophosphinylation reaction of gem-difluoroalkenes that avoids C–F substitution and produces a wide range of α,α-difluorophosphine oxides and functions using
