Thank you everyone for the suggestions. I decided to start with the following
1) potassium via castner
2) SOCl2 - this has already been started but needs improvement
3) LiAlH4
They wore chosen because they present an opportunity for original research (with none particularly well researched for lab synth) and because their
synthesis might present an interest for research labs as well due to price/restrictions/haz chem (I want to shift the emphasis in what I do slightly
towards the professional realm partly because there are not many people doing amateur chemistry, partly because one has to move on)

What about a benchtop micro NH3 plant using the Haber process. Or maybe a small fusion generator, supplying both helium and power to the lab.
btw those suggestions were simply compliments to your ingenuity not serious suggestions, however if you have any ideas.....

The synthesis of O-Phenylenediamine from a phthalate ester via ammonolysis and a duble Hoffman reaction would be a useful synthesis.
O-phenylenediamine would be useful for synthesisizing many useful heterocycles and ligands for use in inorganic chemistry. I am currently working on
this synthesis, but the ammonolysis is taking some time.

Well, o-phenylenediamine, once you have it, is very easily oxidized and so presents problems in purification, handline and storage.
Normally it is prepared starting from aniline, by blocking the 4-position via sulphonation, then nitrating selectively at the 2-position. Removing the
sulphonic acid group at 4 position leaves o-nitroaniline. This is readily reduced to o-phenylenediamine. See Org.Syn.
BTW, I have a Kg of Merck o-phenylenediamine and they store it in dark bottles wrapped in opaque black plastic, because it is light sensitive.
It is also a nasty hepatotoxin, more so than aniline.

some belated organic ideas
The synthesis of sulfoxides (DMSO, DESO, etc), or furfural (I know of the OrgSyn synthesis, but seeing it demonstrated is another thing).

Another idea would be the synthesis of mono nitro toluene isomers and the separation of the isomers along with the production of the respective
toluidines.

actually a serious request would be BF3 in ether, now that would be great!!!

I think BBr3 might be easier to form than BF3? Although they don't have the same properties IIRC.

I think the best payoff would be to put effort into finding a good way to produce ozone. If ozone could be easily produced with enough speed, then it
would make chemical acquisition a lot easier IMO.

I second that. In theory ozone is one of the most amazing and versatile synthesis agents. Nitric and sulfuric acids and their anhydrides in
particular come to mind. However I remain skeptical that it could be produced cheaply in enough molar quantity to be useful in any such syntheses.
The mind cannot decide the truth; it can only find the truth.
