Quote: Originally posted by not_important  | p-dichlorobenzene + AlCl3 gives mostly a mix of the dichlorobenzene isomers, the chlorines seem happy to hop about on the ring but don't like to jump
rings. Careful fractionation of the mix might be able to remove benzene, I've not tried that as several reports stated no ring jumping for Cl although
Br has been stated to ring jump.
If the mixed dichlorobenzene isomers are cooled so the much of the para isomer freezes out, the ramaing mix is a useful not-too-reactive solvent.

I know this is an old thread but I'm interested in this mention of
chlorine jumping around on the ring and turning 1,4 dcb into
1,2&1,3dcb is great news if true. If anyone has any experience or
information about the moving around of halogens on the ring please
enlighten me.
