I was wondering if making an adduct between HMTD and trimethyl borate is possible by simply adding HMTD to trimethyl borate, and then evaporating off
the remaining trimethyl borate
I would try it myself first, however considering the dangers of HMTD i thought it wise to post here first to see if anyone has tried it before or has
any information on the adduct
Could it possibly become even more sensitive due to the electron withdrawing effect of the trimethyl borate taking electron density away from the
peroxide bonds? Or would no adduct form at all?
Sorry if there are any issues with this post, its my first time posting

What about more safe experiment first, like checking whether hexamine forms adduct? Also, triethyl borate is a bit safer than trimethyl (flash point
+11 vs -9°C).
Frankly, idea to combine very sensitive primary and almost pyrophoric borate ester sounds suicidal.
Edit: not pyrophoric, just highly flammable, still bad idea.
If you want to make green flash with boron instead of barium, there is much safer way: fine boron carbide powder burns with pretty green flame.

Are the alkyl borates pyrophoric? I thought only the boranes, but I could be wrong.
In either case, HMTD isn’t a very good peroxide (or EM at the very least) and neither is trimethylborate. If a big green flame is just the desired
outcome, buy a pound of a Barium salt and throw it onto an energetic anion like picrate or even something cheap like chlorate.
