摘要：

Using low-temperature EPR and optical absorption spectroscopy the alpha-aminoxylcarbenium ion I-.+ was directly observed in frozen (77 K) halogenated matrices as a result of electron-transfer oxidation of N-tertbutyl-3-phenyloxazirane 4 by matrix radical cations. The aminoxylcarbenium ion 1(.+) reacts with nucleophilic anions Cl- to form an alpha-chloro-substituted aminoxyl radical 3.
