Metal-free Synthesis of Aryl Amines: Beyond Nucleophilic Aromatic Substitution
A mild and metal-free approach to C?N coupling is described that employs diaryliodonium salt electrophiles and secondary aliphatic amine nucleophiles. This reaction results in direct ipso-substitution of the iodonium moiety and unsymmetrical aryl(TMP)iodonium salts are primarily employed. Moreover, arene substituents and substitution patterns that currently pose a challenge to classical metal-free methods are accommodated and the alicyclic amine nucleophiles used here are unprecedented in other contemporary metal-free C?N coupling reactions.

Synthesis of meta-substituted aniline derivatives by nucleophilic substitution
Substitution by amines of fluorobenzenes containing a meta- substituted electron withdrawing group (EWG), in DMSO at 100 °C over 60 h gave meta-substituted aniline derivatives in isolated yields of up to 98%. The scope of the reaction is explored in terms of reaction conditions and substrates. It is postulated that facile meta-substitutions are facilitated through field stabilisation of the intermediate anion by EWG substituents.
