- 論文の詳細を見る
The paramagnetic species formed by in situ electrochemical oxidation of N-nitroso-2,2,6,6-tetramethylpiperidine (1), N-nitrosodicyclohexylamine (2), and N-nitrosodiisopropylamine (3) in acetonitrile or propionitrile at -30--90℃ have been identified as the radical cations, >N^+=N-O, derived from the parent nitrosamines by one-electron transfer. The radical cations are σ-radicals isoelectronic with the corresponding iminoxy radicals and show long-range couplings to hydrogen atoms, but the value of hyperfine splitting constant of the nitroso-nitrogen (ca. 45G) is the largest known for a nitrogen atom in an organic molecule. The order to stability of the radical cations is as follows : that derived from 1 > that from 2 > that from 3.
