Abstract
In recent years,FeCl3-photocatalyzed direct C-H/Si-H bond functionalization reactions have attracted huge attention.In those transformations,chlorine radical(Cl·)could be generated from FeCl3 via a ligand-to-metal charge transfer(LMCT)/homolysis process under light irradiation.The resulting chlorine radical subsequently acts as a hydrogen atom transfer(HAT)agent to abstract the hydrogen atom of aliphatic C-H,O-H,or Si-H bonds to give the corresponding C/Si/O-centered radicals for various organic trans-formations.In this review,we summarized the recent advances in the application of FeCl3 as a HAT photocatalyst for the C/Si-H functionalization to construct C-C,C-N,C-Si,C-S,C-B,and C-P bonds.
