WebA new and efficient approach for the N-arylation of 8-aminoquinoline amides with diaryliodonium salts has been developed. This chelation-assisted selective C–N cross-coupling reaction gave the desired N-arylated 8-aminoquinoline in moderate to good yields. WebA ‘chain polymerization’ is a chain reaction in which the growth of a polymer chain proceeds exclusively by reaction (s) between monomer (s) and active site (s) on the polymer chain with the regeneration of the active site (s) at the end of each growth step.
