Thank you everyone for the positive feedback, guys.
I want to note a coupla things. Dear Primo! i'm afraid, p-dichlorobenzene won't methoxylate - chlorine is way too unreactive, i've seen many examples of his rxn. At best, the yields are low.
Then, dear Chromic, both these rxn ARE equilibrium, it is just a matter of it being shifted in the proper direction.
Then - brominations. I understand your loathing to work w/Br2, well what about making Br2 w/peroxide and xtracting it w/DCM and then using the soln straight for bromination?
>I wish someone could find a way to make a 4-bromo-2,5-dimethoxy benzaldehyde, then we'd be talking...
What do you mean?
Actually, what i intend to use the alkoxides for is for making interesting stuff from bromovanillin - there's such a wealth of potentially possible compounds here, many quite potent, too - and, depending on the order of alkylations, both 3,4,5 and 2,4,5 can bee produced. What of 4-iPr-2,5-diMeO-PEA, say? It's not even in PiHKAL
- should bee potent at 30-50 mg.
So... Oh, yes, the main thing:
Calcium alkoxide can bee made by dissolving CaC2 in alcohol. If one reacts this soln. w/alcoholic NaOH, he'll get NaOAlk and p'p'tated Ca(OH)2.
Now, THIS is, IMO, the best method: it's shortest, cleanest and can produce a product free of NaOH (BTW, can anyone suggest a way to separate them?)
I don't know about you, bees, but in my country tech grade Ca carbide is widely available and cheap as shit - acetylene generators, y'know.
Can someone please tell me what impurities technical carbide has? (i know some Ca3P2, but what else?)
Well that's it for now, bye,
Antoncho
