The Clemmensen reduction is a chemical reaction which reduce aldehydes and ketones to alkanes.
In my book, it is written that under such conditions, double and triple bonds are not reduced, but my teacher told me of one exception:
α,β-unsaturated carbonyl compounds undergo reduction of both the olefinic and carbonyl group.
But according to my book, when this compound undergoes Clemmensen reduction, the product is pent-2-ene.
Who is correct?
