Title: Finkelstien with NaI+E to produce meth All OTC
Post by: Vibrating_Lights on October 22, 2001, 09:09:00 PM

Could a finkelstien with freebase ephedrine and NaI in acetone be used to produce meth. Would be nice wouldn't it.

It'll probably work if you use DMSO as solvent. ;)

No, the finkelstein reaction transforms alkyl chlorides and alkyl bromides to alkyl iodides. It has no effect on alcohols.

FINKELSTEIN!! #4!!
Hey cillier the swap has been used for ages, you should've known that. Oh wait, you'd have to read a real chemistry text to understand the rxn mechanism, too bad Rhodium's site nor the hive actually explain it  :-[ .
But hey, you'll be suprised how much info is an O-chem book.   :P

Sorry catastrophe

I wasn't really payin attention to what was said (bad Bee!!)

You're absolutely right. The Finkelstein only works with halogenated propenylbenzenes like Chlorosafrole.

I am aware that the swap has been used for years.

I should learn not to post stuff when stoned.....hehe. Thanks for the correction though.
