Fluorine halogen oxide compounds

Fluorine is the most energetic oxidizing element and as such is of prime importance in advanced oxidizers. The fluorine-based oxidizers discussed here include elemental fluorine, compounds containing oxygen and fluorine, nitrogen-fluorine compounds, halogen fluorides, and noble gas fluorides. 

More data on the reaction of oxidative fluorination of polyfluoroaromatic compounds with halogen fluorides can be found in [86]. 

The proposed mechanism of oxidative fluorination of unsaturated compounds by halogen fluorides [84-86] and VF5 [33] includes electron transfer from substrate to halogen fluoride or VF5 as a first step, followed by addition of F" to a radical-cation, leading to formation of a radical and its further oxidation to carbocation (see Eq. 12, pathways A,B). It should be pointed out that this is not the only direction, and the actual mechanism may depend strongly on the substrates and reaction conditions. Other mechanisms, such as a radical process (pathway C), cannot be ruled out. 

These compounds range from the thermally unstable FCIO to the rather chemically inert perchloryl fluoride FCIO3. The structure and properties of this family of compounds resemble those of the halogen fluorides. Therefore, they have to be handled with the same care as elemental fluorine and its chemically reactive fluorides. The halogen oxide fluorides can be prepared by fluorination of halogen oxides with elemental fluorine or with halogen fluoride.

The general concept is that sulfur is introduced into the organic substrate as a direct synthetic precursor of fluorine. Tlte sulfur compound is then treated with a thiophilic, soft electrophilic oxidant, for example electrophilic halogenation agents (NBS, NIS, DBH, Br2, SO2CI2 [148], Fj [149], IF5 [150], BrFj [151], 4-MePhIF2 [152], or nitrosyl cations (NO BF., ) [146] in the presence of a fluoride source (50% or 70% HF-pyridine [143], HF-melamine [144], NEt3 3HF) [147].
