Oxyfluorides of the Heavier Halogens

The compounds also react with Lewis acids to generate cationic species by fluoride ion donation  

Of these compounds, FC103, perchloryl fluoride, is the most stable. It is stable to -500 °C and it does not hydrolyze rapidly. The FC103 molecule has a C3v structure  

Because of its oxidizing strength, it has been used as the oxidant with suitable rocket fuels. 

A relatively large number of oxyacids of the halogens exist. Because of the extensive redox chemistry of these compounds, there is an enormous number of reactions involving them. We will give only an overview in keeping with the spirit and space requirements of this survey.
