We know that
the Friedel Craft reaction occurs in the presence
of aluminium chloride which is Lewis acidic and
the Aniline is a strong base. Therefore, when
aniline is reacted with aluminium chloride in Friedel-Craft’s reaction,
formation of salt takes place. The salt
formation take place as:
The presence
of positive charge on nitrogen deactivates the benzene
ring towards electrophilic aromatic substitution reactions. Therefore, aniline
does not undergo Friedel-Craft’s reaction.
