Reduction of Aldehydes and Ketones to Alcohols

Reduction of Aldehydes and Ketones to Alcohols: Introduction

Reaction principle

In the laboratory, aldehydes and ketones are reduced with metal hydrides (e.g. lithium aluminum hydride (LiAlH4 ) or sodium borohydride (NaBH4 )) to the corresponding alcohols. In industry, aldehydes and ketones are reduced to alcohols by hydrogenation using metal catalysts (nickel, palladium or platinum).

Example:

Reduction of acetone to propane-2-ol with sodium borohydride
