Iron(III)-catalyzed regioselective direct remote C–H carboxylation of naphthyl and quinoline amides was developed using CBr4 and alcohol. The reaction involves a radical pathway using a coordination activation strategy and single electron transfer process. The use of sustainable iron catalysis, selectivity, and the substrate scope are the important practical features.

Various N-o-azidonaphthyl and -azidoquinolylheterocycles decomposed thermally in nitrobenzene and in some cases photolytically in benzene to give the title compounds. Similar cyclisations were effected by the action of triethyl phosphite on the corresponding nitro-compounds. Finally, oxidative ring-closure of some o-acylamidoanalogues of the above naphthalenes and quinolines with performic acid is
