12AX7, I'm ashamed to admit I don't know what that would form. I looked into the matter on google and I gather that it would form a crazy super acid.
Am I correct? Sounds like something nice and safe for the kids to do in the kitchen!

Ya- SbF5 and AsF5 are uber lewis acids, or whatever, basically they'd rather be AsF3 or SbF3, so you can imagine the oxidizing potential available.
HSO3F (fluorosulfonic acid) just adds to the suspense, as it's already quite a strong acid. Wikipedia "superacid" entry has more detail than I shall
go into, being off topic

I have a Kilo of Imidazole...
I have been thinking about looking up to see if diazo chemistry will work well with a secondary amine.

Imidazole is a great buffer, around pH 7, and doesn't have the problems associated with Tris and so on.
Plus, it is fantastic for chelating Ni2+ ions (and probably others) - in fact it is used to elute histidine-linked peptides/proteins from a Ni2+
chelate column.
Also, I am sure it makes some interesting salts with HClO4, HNO3, etc.
Are there recorded instances of where a secondary amine works for diazotation? That'd be new to me....

for Imidazole I found several different organometallic compounds.
Involving Cu, Co, Cr,Fe and Ag.
I will probably try making the perchlorate with some perchoric acid.
I have found some references to doing this neutralization in alchol.
The silver and copper look more promising for an energetic compound. Perhaps I can get the perchlorate to complex with some ammonium persulfate with
added ammonia in the presence of copper.
I will probably try this tonight 
Thanks

Dissolve this in 10% H2O2 and use the resulting solution of WO3 (or H2WO4) for interesting aqueous chemistry experiments. When you add the metal to an
excess amount of 10% H2O2, then in a night time it has dissolved. Only use small amounts at a time, otherwise you may have a runaway, resulting in
decomposition of all H2O2 and foaming of the liquid.

Was not with tungsten, but with tungsten hexachloride, that I made tungsten hexaphenoxide tonight. From Brauer. The tungsten hexachloride I used was
really old and hydrolysed in parts, so I did not attempt purification as tungsten oxide would be contaminating.
Also learned that I really really hate the smell of phenol, especially in my basement.
EDIT: Wolean, just 10% peroxide? No acid?
EDIT: Oh thats weird...the hexaphenoxide is bright red, the isopropoxide which I just made is blue...

Novocaine, that stuff dentists numb your mouth with. There is a thread in this forum about the synth.

Indeed, just peroxide, no acid. The resulting solution, however, becomes somewhat acidic (H2WO4 is an acid).

I must admit, I had my doubts that it would work, but it did.
Also, tungsten hexachloride is fun stuff, if you can get it. From my recent experiments with it it seems like it reacts with alcohols to form blue
compounds, and with phenols to make red compounds. I may have discovered its use as in indicator. All the products are surprisingly resistant to
hydrolysis. The ethoxide has been under water for 4 days now, and there is very little tungsten oxide floating around(its yellow).

I can get some cool cyclics like cyclopropylamine and cyclobutanecarboxylic acid, anything interesting that can be done with them?
I don't know anything about potenially illict uses of them, so if they are used in drugs I will not get them. So let me know if they are!

So , did you ever try a double decomposition to convert
the hydrochloride to the nitrate , perhaps by using
NH4NO3 , or NaNO3 solution , mixed with a solution
of the guanidine hydrochloride ?
If there is an easy conversion to the nitrate , then that
can easily be converted to nitroguanidine by dissolving
the nitrate in cold concentrated H2SO4 , and then dumping
the milky solution over a large excess of crushed ice .
The nitroguanidine can be recrystallized from boiling water .
Nitroguanidine can be reacted with hydrazine sulfate to
form nitroaminoguanidine , which forms heavy metal salts
which are initiators .
Nitroguanidine also can be reduced to aminoguanidine by
powdered zinc and ammonium sulfate , or by electrolytic reduction . The aminoguanidine can be diazotized with sodium nitrite to guanyl azide and
isolated as the picrate ....which is an effective base charge for detonators .
Or the aminoguanidine may be converted to tetracene ,
or 5-aminotetrazole by varying the pH at which the diazotization is performed .
From these various intermediates are routes to many different energetic tetrazoles .

You can't go by sciencelab prices, they are outrageous for anything and everything and I am sure they are just a repack operation. If you want
reference prices use Aldrich, Merck or Acros.
Also significant are whether or not container has been opened, how it has been stored, how old it might be, etc. Second hand reagents under the best
of conditions do not hold their value particularly well as some compounds have a limited shelf life, you clearly cannot guarantee the condition of the
contents, you probably cannot even assay them. Frankly if you called your local/state govt they's make you pay for them to haul them away to a hazmat
disposal site. It's a dead albatross you have there. Not a gold mine. 300 lbs guanidine hcl but you aren't interested in explosives?

Aminoguanidine huh? Okay ...you got it
You may be able to convert the guanidine hydrochloride
via reaction with hydrazine ( in situ from the sulfate) to aminoguanidine . So far as I know the specifics for
this are unpublished and unconfirmed but this seems plausible and would be a worthy experiment .
It seems likely that aminoguanidine bicarbonate could be made and isloated from the reaction mixture of *any* soluble guanidine salt with hydrazine
sulfate having been digested for a time at the appropriate pH , then treated with CO2 or sodium bicarbonate .
See the following thread ,
https://sciencemadness.org/talk/viewthread.php?tid=8144&...
about two thirds the way down the page , see my post
" A possible simplified method for aminoguanidine "
Di and triaminoguanidine compounds should be possible by increasing the amount of hydrazine sulfate proportionally .

How about guanidine perchlorate ?
If that pallet is still collecting dust you could convert some of it to guanidine perchlorate. Get an equimolar solution of NH4ClO4 going at a boil,
and slowly stream in an equimolar amount of NaOH with the loss of ammonia converting to a residual sodium perchlorate solution. Stream in your
Guanidine Hydrochloride with stirring, and you should get guanidine perchlorate precipitating as crystals from the residual sodium chloride.
