A room‐temperature, visible‐light‐driven N‐centered iminyl radical‐mediated and redox‐neutral C−C single bond cleavage/radical addition cascade reaction of oxime esters and unsaturated systems has been accomplished. The strategy tolerates a wide range of O‐acyl oximes and unsaturated systems, such as alkenes, silyl enol ethers, alkynes, and isonitrile, enabling highly selective formation of various
Despite the general success of metal catalysts in modern organic chemistry, the exploration of natural available organic molecules as catalysts still has a strong appeal to scientists because of their green and sustainable advantages. Herein an intermolecular coupling reaction of cyclobutanone oximes with olefins promoted by biowaste gallic acid is reported. Both alkylation and carbonylative alkylation

radical-mediated ring opening of cycloketoxime promoted by diboron compound is reported. This strategy provides alternative catalytic routes for the selective C–C bond vinylation, which provides effective approaches for the preparation of various distal-cyanoalkyl alkenes. The experimental explorations showed that the diboron reagent played important roles during the catalytic cycle. And a reasonable
