Pritchina, Elena A. Gritsan, Nina P. Bally, Thomas 2006 The photochemistry of <i>p</i>-azidoaniline was studied in argon matrices in the absence and presence of oxygen. With the help of quantum chemical calculations we were able to characterize the triplet <i>p</i>-aminophenylnitrene as well as the <i>cis- </i> and <i>trans</i>-<i>p</i>-aminophenylnitroso oxides. It was found that the latter two isomers can be interconverted by selective irradiation and that they are ultimately converted into <i>p</i>-nitroaniline. Although restricted wavefunctions of the nitroso oxides are unstable, CASSCF calculations turned up no evidence for the claimed diradical character of these compounds. Also we found no evidence for dioxaziridines as intermediates of the conversion of the nitroso oxides to <i>p</i>-nitroaniline. application/pdf https://folia.unifr.ch/global/documents/300131 https://folia.unifr.ch/documents/300131/files/bally_mic.pdf eng info:eu-repo/semantics/altIdentifier/doi/10.1039/b511229j info:eu-repo/semantics/openAccess License undefined Physical Chemistry Chemical Physics. - 2006, vol. 8, p. 719-727 info:eu-repo/classification/udc/54 Matrix isolation and computational study of the photochemistry of p-azidoaniline http://purl.org/coar/resource_type/c_6501
