Abstract:
As known that the aromatic nitroso oxydes , intermediates of photochemical oxidation of aromatic azides by oxygen have two isomeric forms - trans ( 4) and cis-( 5). In thermal conditions, these forms quickly perish under the kinetic law of reaction of the first order. It is established that the ArNOO trans –isomer to cis isomerization. In turn, the last undergoes unusual reaction of cyclization of terminal atom of oxygen under the orto-provision of an aromatic cycle with the subsequent monomolecular disintegration of a being formed bicycle (6). Work will be executed with financial support of the Russian Federal Property Fund (a grant of the Russian Federal Property Fund ¹ 12-07-00324-a and ¹ 13-03-00201-a)
