Visible-light-induced 1,2-alkylarylation of alkenes with a-C(sp3)–H bonds of acetonitriles involving neophyl rearrangement under transition-metal-free conditions
An efficient visible-light-induced difunctionalization of alkenes with a-C(sp3)–H bonds of nitriles is described for the constructing of diverse 5-oxo-pentanenitriles under transition-metal-free conditions. This protocol proceeds via the functionalization of C(sp3)–H bond and radical addition/intramolecular 1,2-aryl migration processes, which features a wide scope of substituted α,α-diaryl allylic
