We describe the preparation of m- and p-substituted phenyl azides which, on treatment with trifluoromethanesulfonic acid in chloroform (and only in one case, after adding trifluoroacetic acid) at 0 °C, gives rise to the intermediate phenylnitrenium

Phenyloxenium Ions: More Like Phenylnitrenium Ions than Isoelectronic Phenylnitrenes?

Autor: Patrick J. Hanway, Arthur H. Winter

Publikováno v: Journal of the American Chemical Society. 133:5086-5093

The geometries and energies of the electronic states of phenyloxenium ion 1 (Ph-O(+)) were computed at the multireference CASPT2/pVTZ level of theory. Despite being isoelectronic to phenylnitrene 4, the phenyloxenium ion 1 has remarkably different en

Computational studies of the properties of phenyloxenium ions — A comparison with phenylnitrenium and phenylcarbenium ions

Autor: Michael Novak, Stephen A. Glover

Publikováno v: Canadian Journal of Chemistry. 83:1372-1381

Properties of phenyloxenium ion 13a, phenylnitrenium ion 14a, and their 4-methyl and 4-phenyl analogues have been studied at the HF/6-31G* and pBP/DN*//HF/6-31G* levels to explain differences in their relative ease of formation and their stabilities.
