Ph.toinduced ligand-to-metal ch.rge transfer(LMcT) h.s emerged as an effective strategy for synth.sizing organic molecules in a sustainable manner. h.wever, th. majority of existing reports on selective c(sp^(3))–h.bond functionalization via ph.toinduced LMcT focus on th. use of late transition metals or rare-earth.metals for radical additions or cross-couplings. In contrast, th. utilization of ph.toinduced LMcT with.3d early transition metals poses a significant ch.llenge. h.rein, we describe an unprecedented approach.to allylic c(sp^(3))–h.addition to aldeh.des, employing ch.omium(cr) complexes as catalysts th.ough.visible-ligh.-induced LMcT. By investigating th. reaction path.ay th.ough.various mech.nistic studies, including radical trapping, kinetic isotope effect(KIE) analysis, and transient absorption spectroscopy, valuable insigh.s h.ve been gained. Th. proposed mech.nism suggests th. intermediacy of bromine radicals th.ough.h.molysis of th. cr–Br bond. Notably, th.s protocol expands our understanding of th. ph.toch.mical properties of earth.abundant cr complexes.
