From memory, that book went in at least four different directions with fluorine compounds. Parts are about increasing specific impulse; parts are about increasing density impulse (fluorine's very dense); parts are about formulating oxidizers hypergolic with kerosene or with hydrogen; parts are about formulating oxidizers for deep space probes, with a melting/boiling point range matched to that thermal environment.
O3F2 is the one that if you add it to liquid oxygen, it makes hydrogen/oxygen combustion hypergolic.
There's also adding a bit of Flourine to one of the Fuming Nitric Acids to make it easier to handle, because of the flouridation of the surface of the tanks.

O3F2 sounds like it'd be hypergolic with engineers. Nope.
Engineers. Asbestos. Sand.
Can confirm 'Nope'.
Its probably hypergolic even with Nope. ;-)
