acetic anhydride reaction with primary amine
Which anhydride is used in a carboxylic acid reaction?
Because many anhydrides are made from the coupling of two carboxylic acids, reactions using anyhydrides waste one equivalent of the carboxylic acid as a leaving group. As a consequence, reactions are only commonly performed with inexpensive, readily available anhydrides, such as acetic anhydride or benzoic anhydride.
Are anhydrides reactive to nucleophilic attack?
Anhydrides are highly reactive to nucleophilic attack and undergo many of the same reactions as acid chlorides that were explored in section 21.4. Although slower reacting than acid chlorides, anhydrides react with water to form carboxylic acids, with alcohols to form esters, and with amines to form amides.
How do acid anhydrides react with amines to form amides?
Acid Anhydrides react with amines to form amides General Reaction Example 1: Mechanism 1) Nucleophilic Attack by the Amine 2) Deprotonation by the amine 3) Leaving group removal Contributors Prof. Steven Farmer (Sonoma State University) Back to top Acid Anhydrides react with alcohols to form esters
How do acid anhydrides react with water?
The chemistry of acid anhydrides is similar to that of acid chlorides, although anhydrides react more slowly. Thus, acid anhydrides react with water to form acids, with alcohols to form esters, with amines to form amides, and with LiAlH 4 to form primary alcohols. Only the ester- and amide-forming reactions are commonly used, however.
