Hoffman degradation of benzamide

Nettet6. apr. 2024 · We can use Hoffman bromamide degradation reaction to obtain amines from corresponding amides with the loss of one carbon. Complete answer: To convert Benzoic acid to Aniline, we need to remove the -COOH group from the benzene ring and need − N H 2 group attached to that carbon in the benzene ring. NettetHofmann Elimination Mechanism. Step 1: The amine is treated with methyl iodide ( exhaustive methylation ) to form the quaternary ammonium iodide salt. Step 2: Now the iodide is treated with excess silver oxide to form silver iodide, silver oxide ion, and silver hydroxide (by deprotonation of water) Step 3: Elimination of β hydrogen from the ...
