When cyclohexanone reacts with dimethylamine in the presence of a catalytic amount of acid (with con — Amines Chemistry Question

💡 Solution & Explanation

The reaction of a secondary amine (such as dimethylamine) with a ketone (such as cyclohexanone) under acidic conditions yields an enamine. The initial nucleophilic attack forms a hemiaminal that loses water by removing an alpha-hydrogen from the cyclohexyl ring, resulting in a carbon-carbon double bond adjacent to the nitrogen.
