[edit]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)

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 The comments may be irrelevant or outdated; if so, please feel free to remove this section.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. |

[edit]The page only shows attach ispo to a leaving group (fair enough, it is the most common type). It mentions vicarious nucleophilic substitution but not the broader concept of nucleophilic substitution of hydrogen, where the nucleophile attacks elsewhere. Should we expand? Here are a couple of reviews (1st one open access): doi:10.1515/pac-2017-0108, doi:10.1021/cr020086+ Project Osprey (talk) 14:24, 26 September 2024 (UTC)
