Back in the day I used 1.0M TEA in hexane for organic synthesis work and didn’t
find it difficult to work with using basic precautions required for pyrophoric
materials.
The XLR-99 engine that powered the X-15 burned LOX and NH3 and suffered hard
start issues until they dissolved lithium in the NH3 prior to injection.
I don’t know if that resulted in a fuel that was hypergolic with LOX and
possibility that the effect could extend to N20.
If I were to speculate, NTO and NO2 should be soluble in N20.
The stability and properties of the mixture would only be guess on my part.

Subject: [AR] Hypergolics with N2O?
Does anybody know about chemicals which are hypergolic with N2O? I know TEA and
TEB are, but that's nasty stuff. Someone told me that Silane (SiH4 and the
heavier molecules) may be hypergolic as well. That's also nasty stuff, but more
available that TEA. It might be soluble in conventional fuels like
Ethane/Ethene/Propane etc. But I haven't found much about the hypergolic
behavior...
