An efficient and regioselective remote C(5)–H nitration of 8-aminoquinoline amides by using the economical and nontoxic Fe(NO3)3·9H2O as promoter and nitro source has been developed. Furthermore, when CuCl2·2H2O was used as a catalyst, 8-aminoquinoline amides dominantly underwent bisnitration to give 5,7-dinitro-8-aminoquinoline amides. Notably, this is the first example in which Fe(NO3)3·9H2O plays
