I guess TFSE isn't working properly, I couldn't find the post, but it was on a thread about peracetic acid, where unnilhexium made mention of his amination technique using I2 tincture. I don't know if that was a unnilhexium original or not, he was just the first bee I saw posting about it. Anyhow, for those of you worried about side reactions, the residual I2 seems to form some kind of alu-halide, as the red color leaves the solution during the amalgamation. Also, the tincture adds about 15ml of water to the reaction, which should keep Osmium off your case
BTW, it important to periodically shake the tincture bottle, to break up the mercury blob so that it can react. Also, make them as far in advance as possible. They can be made weeks, months or years in advance, IT'S JUST TOO EASY!!!!!!!!!!!!! Isn't that so much nicer than making or buying HgCl2?
