I have tried to make this acid via the procedure mentioned in orgsyn and things were ok
http://orgsynth.org/orgsyn/orgsyn/prepContent.asp?prep=CV2P0...
I searched beilstein and found other methods but in german
I need help in their procedure plz
The orgsyn method is multistep procedure and depends on o-chloro nitrobenzene where the disulfide is obtained first and then oxidized and chlorinated
using nitric acid and chlorine then finally reduced using iron and acetic acid
The other methods depends as long as I know on rearrangement of phenylsulfamic acid in such a manner that yields ortho isomer and not the para isomer
(I would like to know the details of such reaction plz
