Photolysis of 4-azido-pyridine and -quinoline in hydrohalogenoic acids gave the 3-amino-4-halogeno compounds (2) via azirine or azacycloheptatetraene intermediates, whereas their N-oxides (4), under similar conditions, gave the 4-amino-3-halogeno compounds (5) presumably via nitrenium ion intermediates.In the 3-azidoquinoline and 4-azidoisoquinoline series, both free bases (6a, 8a) and N-oxides (6b, 8b) gave similar results to 4-azidopyridine and -quinoline N-oxides (4).
