Aniline
does not undergo Friedel craft reaction because the reagent
AlCl3
as an electron deficient acts as Lewis base and only attacks on the sole pair
of N (nitrogen) present in aniline to make an insoluble complex that
precipitates out and the reaction does not proceed. Since Freidel craft
reaction requires Lewis acid as catalyst to the said reaction, it does not
apply to aniline.
AlCl3 a reagent which was used by Friedel Craft in alkylation and acylation. It increases the probablility and possibility of the aromatic substitution.
