Inspired by recent precedents on visible-light-induced functionalization of unactivated alkanes, 27 we wondered about the feasibility that combining visible-light-induced photoredox catalysis with Cr(III) catalysis to enable the gem-difluoroallylation of unactivated alkanes (Scheme 1c). In view of the fact that Cr(III) is a good one-electron acceptor, we anticipated that this proposal could be realized through a single electron-transfer (SET) process between photoredox catalysts and Cr(III) under the irradiation of visible light (380 -740 nm). Moreover, the in situ generated organochromium nucleophile was added to alkenes with a concurrent defluorinative process instead of an addition to the carbonyl group in aldehyde in the classical NHK reaction. If successful, not only the scope of classical NHK reaction could be largely expanded, but also the chemistry of Cr(III) catalysis will be enriched.
