Twisted Diarylnitroxides: An Efficient Route for Radical Stabilization

New strategy for the molecular design of stable diarylnitroxides was elaborated based on the insertion of a bulky substituent into the ortho-position of the phenyl ring thus disturbing its conjugation with the radical center. A series of new twisted diaryl nitroxides with tert-butyl and trifluoromethyl substituents in different positions and combinations was obtained and fully characterized. Electron spin resonance (ESR) and density functional theory (DFT) studies confirmed that the ortho-substituted phenyl ring is removed from the conjugation; the O–N–C–C torsion angle was shown to be dependent not only on the bulkiness of the ortho-substituent, but it is also influenced by the electron-donating or electron-withdrawing ability of the substituents in both phenyl rings. These nitroxides constitute the first examples of stable diarylnitroxides with a vacant para-position on the phenyl ring. The new approach will broaden the scope of available stable diarylnitroxyl radicals, which are practically important.

Diarylnitroxide diradicals: Low-temperature oxidation of diarylamines to nitroxides

A low temperature method, in which the progress of the oxidation of secondary diarylamines with DMDO at low temperatures is monitored by magnetic resonance spectroscopy (EPR and NMR) and magnetic studies by a Superconducting Quantum Interference Device (SQUID), is developed for preparation of the first m-phenylene based diarylnitroxide diradical. EPR spectroscopy and magnetic studies (SQUID) indicate that the diradical in the dichloromethane matrix predominantly adopts anticonformation (2A-anti) and possesses triplet ground state. Similar oxidation experiments for conformationally constrained aza[1 4]metacyclophane provide evidence for the formation of small amounts of the corresponding diarylnitroxide diradical. Both diarylnitroxide diradicals could only be detected at low temperatures (-80°C and below).
