ChemInform Abstract
In order to develop a synthetic approach to the title compounds (II) the matrix photolysis of the azidophenols (I) is investigated by IR spectroscopy. In all cases the expected ring expansion occurred and the azepinones are formed at low temperature. Attempts to isolate the azepinones by warming result only in polymeric products.
