Conclusions
-
1.
In the reaction of different types of nitrones with xenon difluoride in methylene chloride, nitroxyl radicals containing one or two fluorine Β-atoms are formed.
-
2.
A method is proposed for obtaining stable nitroxyl radicals containing fluorine Β-atoms.
-
3.
The values of the HFI constants aF at the fluorine Β-atom are very sensitive to various structural factors and vary over a wide range, from 20 to 60 Oe.
