Question

Question: Predict the products of the wolff-Kishner reduction reactions below. Provide the electron pushing mechanism for each, beginning from the hydrazone intermediate.

Short answer

.

Step-by-step solution

Wolff-Kishner reduction

Aldehydes and ketones can be converted into a hydrazine derivative by reaction with hydrazine. These hydrazones can be further converted to the parent alkane by action of base and heat. Both these reactions together are called Wolf-Kishner reduction

Mechanism (a)

Mechanism (b)

Mechanism (c)

Mechanism (d)

Explanation for common feature

All these reactions follow the same mechanistic pathway.
