Is the SnAr mechanism really correct? I always learned that nucleophilic addition was the rate-determining step (hence the reason aryl fluorides react fastest due to polarization of the bond) and that the reaction was under kinetic control. Thoughts? — Preceding unsigned comment added by 129.67.118.139 (talk) 14:15, 19 August 2012 (UTC)[reply]

Assessment comment[edit]

The comment(s) below were originally left at Talk:Nucleophilic aromatic substitution/Comments, and are posted here for posterity. Following several discussions in past years, these subpages are now deprecated. The comments may be irrelevant or outdated; if so, please feel free to remove this section.

This sentence in the article " the nitro group is an activator toward nucleophilic substitution, and an ortho/para director" is questionable. In another wikipedia article on Electrophilic Aromatic Substitution nitro is under the group categorized as a meta director.
