Formation of nitroxyl radicals containing fluorine Β-atoms in the reaction of nitrones with xenon difluoride

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