Chemical reaction which adds an acyl group (R–C=O) to a compound

In chemistry, acylation is a broad class of chemical reactions in which an acyl group (R−C=O) is added to a substrate. The compound providing the acyl group is called the acylating agent. The substrate to be acylated and the product include the following:

A particularly common type of acylation is acetylation, the addition of the acetyl group. Closely related to acylation is formylation, which employ sources of "HCO+ in place of "RCO+".

Because they form a strong electrophile when treated with Lewis acids, acyl halides are commonly used as acylating agents. For example, Friedel–Crafts acylation uses acetyl chloride (CH3COCl) as the agent and aluminum chloride (AlCl3) as a catalyst to add an acetyl group to benzene:[2]

This reaction is an example of electrophilic ar...
