- Reaction of indolinonic aminoxyls with nitric oxide
-
2-Methyl-2-phenyl-3-oxoindolin-1-yloxyl and 2-methyl-2-phenyl-3-aryliminoindolin-1-yloxyl radicals react with nitric oxide in the absence and presence of oxygen to form both substituted and unsubstituted N-nitro and N-nitroso stable compounds as the main

- On the Reaction of Aminoxyls with Dioxiranes
-
In the reactions of dimethyldioxirane (1a) and methyl(trifluoromethyl)dioxirane (1b) with 2,2,6,6-tetramethylpiperidinyl-1-oxyl (2) (TEMPO) in acetone, the corresponding methoxyamine 1-methoxy-2,2,6,6-tetramethylpiperidine (5) is produced in ≥98% yield, b

- ACID TREATMENT OF 2-METHYL-2-PHENYL-3-OXO-INDOLIN-1-OXYL
-
2-Methyl-3-oxo-indolin-1-oxyl 10 with trifluoroacetic acid gives the disproportionation products 11 and 12.With dry HCl or HBr it undergoes halogenation and deoxygenation and yield halogenated indoxyls 13a-c and 14a-c, and with HI it undergoes deoxygenation to indoxyl 11 or reduction to hydroxylamine 15, depending on the reaction solvent.A deoxygenation mechanism is proposed on the basis of experimental evidence.

- HOMOLYTIC SUBSTITUTIONS IN INDOLINONE NITROXIDE RADICALS-III REACTIONS WITH TERBUTOXY AND METHYL RADICALS
-
Nitroxide radicals 1a-c react with terbutoxy radical to form terbutoxy substituted radicals 2, 3 and 4.The reaction mechanism is interpreted in terms of homolytic substitution.The terbutoxy substituted nitroxides can be easily oxidized to quinoneimine N-o
