MaDMAx; yes, I have seen bromine in all its many layers of packaging before (from Sigma-Aldrich; if I'd known how hard it was to ship, I think it may have walked from my University with me...). The MSDS is a particularly nice one, a search on
http://www.chemexper.com/
brings it up.
Yellium; no, I'm not trying to make 2C-B (although it's a nice thought
), I need bromine as it's much easier to work with (though more dangerous) than gaseous chlorine, for the link given in my first post (brominating an aliphatic carbon rather than an aromatic one). I am considering Iodine monochloride as it is a liquid, and will give up the chloride ion as the nucleophile to attack the alpha carbon. It's quite expensive though...
Elementary; if I can't get elemental bromine that is exactly my (last resort) plan. I think it's actually cheaper that way anyway, though I don't really fancy doing it. NaBr is cheaper per mole of bromine than bromine itself!
I may try ordering it from overseas; I found a company (the largest bromine manufacturers in the world) that sells bromine in 8000L quantities (that's 24,000 tons)!
