This section simply aims to show some further aromatic reactions which do not necessarily fit into the earlier parts of the chapter.

The S_RN1 Reaction

The terminology here is built up the same way as for nucleophilic substitutions ;

Substitution _{Radical Nucleophilic} unimolecular.

As it involves radicals it follows the general pathway for radical reactions - Initiation, Propagation, Termination. A relatively common occurrence of the S_RN1 mechanism is shown below;

Reacting CO₂ with aromatic rings

A useful reaction, as a carbon-carbon bond is formed onto an aromatic ring, in a very precise position;

A Synthesis involving two Friedel-Crafts Steps

This is intended to show Friedel-Crafts chemistry in action, and also to show that a Friedel-Crafts acylation does not necessarily need an acid halide. Some of the steps use reactions that may be unfamiliar at this stage - do not worry about these, but look out for them in further sections of this site!
