Thus, (CH 3 CO) 2 O is called acetic anhydride. Mixed (or unsymmetrical) acid anhydrides, such as acetic formic anhydride (see below), are known. One or both acyl groups of an acid anhydride may also be derived from another type of organic acid, such as sulfonic acid or a phosphonic acid.ixed (or unsymmetrical) acid anhydrides, such as acetic formic anhydride (see below), are known.

Nucleophilic acyl substitution describe a class of substitution reactions involving nucleophiles and acyl compounds. In this type of reaction, a nucleophile â such as an alcohol, amine, or enolate â displaces the leaving group of an acyl derivative â such as an acid halide, anhydride, or ester.nder basic conditions, a nucleophile (Nuc) attacks the carbonyl group of the acyl compound 1 to give tetrahedral alkoxide intermediate 2. The intermediate collapses and expels the leaving group (X) to give the substitution product 3.
