Nitration with nitryl fluoride
I know it's a bit out of the league of most amateur chemists (due to the fact that you need F2 to make it), but has anyone here had any
experience/knowledge using nitryl fluoride (FNO2)?
Thanks.

This patent gives an industrial-type prep for FNO2 using CoF3 & N2O4 in a heated Monel tubular reactor: http://www.pat2pdf.org/patents/pat3259460.pdf. One difficult component is the need for a liquid N2 trap in the output stream. There are a number
of earlier patents as well.
The fluorine source in this patent is the cobalt fluoride salt.
I worked in fluorine chemistry for many years (on the marketing side) & we used both anhydrous HF as well as KF halex exchange but never nitryl
fluoride.

There's a company called Fluorochem that specializes in this sort of thing.
IIRC they are on the West coast of the US.

Oh, i have no doubt in my mind that I can make nitryl fluoride. I have a nice paper on how to do it on a lab scale (The Preparation of Nitrosyl
Fluoride and Nitryl Fluoride by Albert V. Faloon and William B. Kenna JACS, Vol 73, issue 6, pp 2937 - 2938). I'm just wondering if anyone here has
used it in any nitrations and how successful they were?

The preparation of both compounds on a lab scale is described in detail in Brauer, (Handbook of Preparative Inorganic Chemistry).
I would also be amazed if this were not covered in Inorganic Syntheses.
