A simple protocol of iron(III)-catalyzedhalogenation of 8-amidoquinolines in water under mild conditions was developed, affording the 5-halogenlated products in good to excellent yields up to 98%. The reaction mechanism most likely involves a single-electron transfer (SET) process.

A highly efficient and convenient strategy has been developed for remoteC–H bond halogenation of 8-aminoquinolines in good to excellent yields under transition-metal-free conditions. The reaction tolerates a variety of functional groups and can potentially be scaled up.
reaction tolerates a wide scope of alkyl and aryl amides as well as (hetero)aryl boronic acids, generating the corresponding arylation products in good to excellent yields. Furthermore, the one‐pot alkenylation, alkynylation, thiolation and phenoxylation of quinolines on the C5 position can be efficiently realized using this brominated quinoline amide molecular platform. Thus, the method shows high practical
