Conclusions
-
1.
Bromination of 2,2,6,6-tetramethyl-4-oximinopiperidine by N-bromosuccinimide and subsequent oxidation yields 2,2,6,6-tetramethyl-1,4-dibromo-4-nitropiperidine.
-
2.
The reaction of 2,2,6,6-tetramethyl-4-nitropiperidine with iodine gives 2,2,6,6-tetramethyl-4-iodo-4-nitropiperidine.
-
3.
Oxidation of 2,2,6,6-tetramethyl-4-bromo- and 2,2,6,6-tetramethyl-4-iodo-4-nitropiperidines by perbenzoic acid yields the corresponding nitroxyl radicals.
