    Can anyone show me the mechanism for both steps:
    http://prntscr.com/a7sfzg

    Its probably really simple but im just a bit confused
    is it just the same as nitration of benzene?
    Im just a bit unsure.



    Any help would be nice, thank you

    Yeah, bog standard nitration but strong acid also opens the acid anhydride

    If youre doing A2 chemistry your not going to have to remember the mechanism but rather reagents used!

    Check this out nitration in benzene

    Read a few scientific journals and the mechanism seems to be quite different than just a normal nitration in benzene.

    Any ideas?

    Its definitely not the same as the nitration of benzene! Asked my lecturer and he said its not. Im in my 2nd year of uni so I imagine its quite a difficult mechanism.

    By not the same as nitration of benzene, do you mean the nitration of this involves the acid anhydride in the mechanism, i.e. the ring opening is not a standalone reaction?

    I suggest an intermediate acyl nitrate is formed (with concomitant anhydride ring cleavage) which directs the nitro group ortho to a carboxyl group.

    I think both aha, I cant find it in any organic textbook nor any research paper so
