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
