A visible-light-driven iminyl radical-mediated C-C bond cleavage and functionalization of cycloketone oxime esters have been accomplished to give distal cyano pyridines such as I [R1 = H, Me, Bn, etc.; R2 = H, Me, Ph, etc.; R3 = H, 4-Me, 5-Me; R4 = H, Ph, 4-ClC6H4; R5 = H, 4-MeC6H4; n = 1, 2, 3, etc.; X = O, CH(Ph), CH(OBn), etc.] and distal cyano alkenes such as II [R6 = COOEt, Ph, 2-naphthyl, etc.; R7 = H, Me, Bn, etc.; R8 = H, Me, Ph, etc.]. This protocol is simple and does not require expensive and toxic photoredox and/or transition-metal catalysis, providing a novel catalyst-free strategy for alkylation, allylation, vinylation and alkynylation through addition of C(sp3)-centered radicals to various unsaturated acceptors. The com. available and photoactive Hantzsch ester effectively serves as an electron donor, as well as a hydrogen atom source.
