Web26 Jan 2016 · 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. WebFriedel-Crafts reactions are limited to arenes as or more reactive than mono-halobenzenes; Other sources of acylium can also be used such as acid anhydrides with AlCl 3; Summary of Limitations of Friedel-Crafts acylations: Acylation can only be used to give ketones. This is because HCOCl decomposes to CO and HCl under the reaction conditions.
