Mechanism of Wolff-Kishner Reduction…

Mechanism of Wolff-Kishner Reduction:
(i) The hydrazone formation involves the nucleophilic addition of the hydrazine to the carbonyl carbon, followed by elimination of water. The resulting hydrazone is a stable compound.
(ii) The hydrazone is then treated with a strong base, forming a carbanion intermediate.
(iii) The process involves migration of the alkyl group from the nitrogen atom to the carbon adjacent to the carbonyl carbon, breaking the carbon-nitrogen bond in the process.
