Photoinduced dimeric metal complexes have been extensively utilized in halogen atom transfer (XAT) reactions. In this study, we successfully achieved the abstraction of ester group from cyclobutanone oxime esters via iron(I)-dimer catalysis under near-infrared (NIR) light (730 nm) excitation, enabling efficient synthesis cyanoalkylated alkenes, quinazolinones, and 3,3-disubstituted oxindoles. Mechanistic investigations confirmed NIR-induced functional process.
