Friedel craft alkylation of aniline
WebJan 26, 2016 · 11 I know that Friedel-Crafts reaction (either alkylation or acylation) fails with phenol and aniline, due to formation of a coordinate bond between Lewis acid catalyst and the lone pair of the respective functional group. But I have read that even benzoic acid fails to undergo this reaction. I couldn't think of a reason for this.
