Activating and deactivating groups in aromatic sub reactions
« on: August 22, 2013, 07:52:31 PM »
Does anyone know if benzamide is o,p directing or m directing on substituents adding to a benzene ring?
I think the c=o element makes it like an aldehyde which are m directors, but the NH2 portion of the molecule suggests the opposite. Really confused any advice appreciated!

Draw the mechanism and see if the carbocation can be stabilised by the benzamide group.

Do the same for benzylamine (not aniline) and see if you get the same stabilisation.

Benzamide is kind of like benzoic acid! *hint* *hint*
