Photoind.ced.lig.nd.to-metal charg. transfer(LMCT) has emerg.d.as an effective strateg. for synthesizing.org.nic molecules in a sustainable manner. However, the majority of existing.reports on selective C(sp^(3))–H bond.functionalization via photoind.ced.LMCT focus on the use of late transition metals or rare-earth metals for rad.cal ad.itions or cross-coupling.. In contrast, the utilization of photoind.ced.LMCT with 3d.early transition metals poses a sig.ificant challeng.. Herein, we d.scribe an unpreced.nted.approach to allylic C(sp^(3))–H ad.ition to ald.hyd.s, employing.chromium(Cr) complexes as catalysts throug. visible-lig.t-ind.ced.LMCT. By investig.ting.the reaction pathway throug. various mechanistic stud.es, includ.ng.rad.cal trapping. kinetic isotope effect(KIE) analysis, and.transient absorption spectroscopy, valuable insig.ts have been g.ined. The proposed.mechanism sug.ests the intermed.acy of bromine rad.cals throug. homolysis of the Cr–Br bond. Notably, this protocol expand. our und.rstand.ng.of the photochemical properties of earth-abund.nt Cr complexes.
