Photoinduced Ligand-to-Metal Charge Transfer Enables Iron-Catalyzed Site-Selective Oxime Ether Construction at C(sp ³ )–H Bonds of Silanes

Herein, we present a novel iron-catalyzed regioselective C-H functionalization of silanes for the construction of oxime ethers enabled by photoinduced ligand-to-metal charge transfer (LMCT). This transformation proceeds under mild conditions using an inexpensive and commercially available iron catalyst, without the need for costly photocatalysts. The protocol features excellent site selectivity, broad substrate scope, high efficiency, and good scalability, offering a practical and economical route to organosilicon-based oxime ethers.
