When Reagents Attack!
Well, since I was just talking about a reagent that can potentially take off without warning, I wanted to solicit vivid experiences from the crowd. What's a compound that you've made that did something violently unexpected? I can recall making some para-methoxybenzyl chloride in grad school (for a protecting group; I was running out of orthogonal protecting groups by that time). It's not hard - take the benzyl alcohol and some conc. HCl and swoosh 'em around. But the product you get by that method isn't the cleanest thing in the world, and on storage, well. . .a vial of it blew out in my hood after the acid had had a chance to work on it.
My most vivid reagent-gone-bad story is probably this one; that's a time I literally came down counting fingers. What other things have you had turn on you?
