Title: 4-iodotoluene synthesis
Post by: lasset on April 27, 2009, 04:15:14 PM

So basically it's a Sandmeyer reaction, but I've got a scheme which dosen't use a copper catalysit.

The simplified procedure looks like this: p-toluedine is dissolved in HCl then a NaNO3 solution is added. Then I add carbamide, then KI solution(everything is done in a low temperature) Then I heat the mixture and add NaOH.

So I would like to know what is the function of carbamide and NaOH.

Is it theoretical or did you actually synthesize the required compound like this?

Just searching around, it looks like urea (carbamide) is there to get rid of any leftover nitrous acid.

I really synthesized it like this
