A unified strategy for intermolecular remote C(sp3)-H and C-C vinylation of O-acyl oximes with vinyl boronic acids has been achieved. This strategy is enabled by photoreductive generation of iminyl radicals from O-acyl oximes under irradiation by visible light. The translocated carbon-centered radicals, which are generated from the iminyl radicals through 1,5-hydrogen atom transfer or C-C cleavage, can be vinylated with vinyl boronic acids. This strategy opens up a new approach to remote functionalization via C(sp3)-H and C-C cleavage and provides an efficient and versatile solution to the synthesis of ?-vinylation of ketones and nitriles.

Irradiation of benzyldicarbonyl(η5-cyclopentadienyl)iron complex (2) leads to homolytic cleavage of the Fe-C bond.In the presence of activated alkenes, radical addition occurs, and both saturated and unsaturated addition products 7-9 are formed.Photolysis of alkyliron complexes 2, 3, and 20 in the presence of acrylonitrile leads to the same products as the irradiation of the respective acyliron complexes 28-30.This indicates that, under photolytical conditions, alkyl and acyl complexes are in equilibrium with each other.
