Summary |
Chapter 12 : Reactions of Arenes. Electrophilic Aromatic Substitution |
The structure and properties of aromatic systems were discussed in Chapter 11.
Now it is time to visit their chemical reactions.
The arene system contains an electron rich C=C system which react with
electrophiles via a substitution pathway (to preserve aromaticity) via what
is known as electrophilic aromatic substitution :
An electrophile, E+, is an electron poor species that will react with an electron rich species (the arene)Electrophilic aromatic substitution reactions are the very important class of reactions that allow the introduction of substituents onto arenes.
Aromatic because the reaction is characteristic of aromatic systems.
A substitution implies that a group is replaced (usually H).
