Amalgum,I fully understand you train of thought.
After many months of reading/theoretical experimenation with trying to produce HI,halogenate and reduce ephedrine in a devided electro cell,IT HAS JUST DAWNED ON ME!!
Rhod` You have indicated in a previous post in another thread that the halogenation part of the rdxn is not where
the time is needed,but rather when the HI acting on the iodo-intermediate.Is this right?
Do you have any idea as to how quickly the first step of the rxn proceeds?
Can the same be said for the need of a certain temp?
In other words,will ephedrine form its iodo counterpart, using HI as the halogenation agent,under ambiant temps?
Now Im sure there are other ways to iodinate ephedrine without the need for HI.Orgy rcently mentioned PI3 as being able to do this quicker.Ive read a few refs mentioning tri-iodides e.g the vanalin thread on your page.
I know there are many alternative ways to halogenation,a few mentioned on your page.
I have some refs on the selective dehalogenation/reduction
of aromatic compounds in electrochemical environments,
which see many uses in environmental science,and which dont seem any harder or less applicable to home cchemistry scenarios then electrochemical HI production.
Do you think it would be feasible to simply halogenate your ephedrine{(chloro,bromo,iodo)
Anyone interested should search for Electrochemical De-halogenation of aromatic compound.
I have a great feeling about applying this to the kitchen,
as I see it as by-passing many a pitfall encountered when setting out for the HI style rxns.
I also see it as being a high yielding,high purity method of
hydrogenation without the need for noble metal catalysts as electricity and carbon cathode is all that is required.
Think of it,as a cross between common HI reductions, WizardXs hydrogenations and Festers electro flop,except we need no pressure,we need no external hydrogen,no P,no Platinum et al.Less time,less chems alround.
I can see it now:Bromine spa tablets,Activated carbon,a labskin condom and a 12volt battery and we have meth by the bucket load.
I will clarify,be more formal if needed.
Any comments?
Thankyou in advance.
P.s I have mentioned this in the past,with little or no response.

I am scared to move it to one of the chemistry forums for I hold great fear of ridicule.
