Iron-catalyzed C–H bond functionalization into oxime ethers via photo-induced ligand-to-metal charge transfer†

We have developed a novel strategy for Fe-catalyzed C–H functionalization into oxime ethers through photo-induced ligand-to-metal charge transfer (LMCT). The method avoids the need for photocatalysts and bases, utilizing a cheap and readily available catalyst under mild conditions. It offers a broad substrate scope, scalability, and high efficiency, providing a promising and cost-effective strategy for synthesizing oxime ethers from simple and abundant starting materials.
