Acquire trimesic acid.

All of the online sources of trimesic acid I can find are prohibitively expensive. Would a synthesis from toluene be the best option (The only problem with that is that I cannot get aluminum trichloride)?

I had to Google that one, but how much do you need? And do you have a reference to the synth from toluene? If all you need is a little maybe you can work out something with in situ generated AlCl3?

There’s some discussion in the benzene sticky thread about disproportionation of toluene to benzene and mesitylene using catalytic AlCl3, and some speculation about generating it in situ, but I don’t know if anyone ever got around to trying it, because I haven’t read all 14 pages of that thread.

Not much, only 10-20ml.
Thanks Mackolol that route looks better than using methyl halides. Mesitylene to trimesic shouldn't be to bad, I plan on following a procedure for tolulene oxidation, except increasing the amount of KMnO4. That seems like the best option.

Toluene (dry) + Aluminium (even fol works) + iodine. Boil boil boil and then boil it a little bit longer.

In situ formed AlI3 works even better then AlCl3, workup is by simple fractional distillation.

I have my doubts about Osmium but I think the chemistry there makes sense.
