WebCarboxylic acids, acid halides, esters, and amides are easily reduced by strong reducing agents, such as lithium aluminum hydride (LiAlH 4 ). The carboxylic acids, acid halides, and esters are reduced to alcohols, while the amide derivative is reduced to an amine. Most reductions of carboxylic acids lead to the formation of primary alcohols. Web9 jan. 2024 · The reduction of oximes or oxime ethers and esters to primary amines is a useful synthetic transformation that is used as a substitute for direct reductive amination to convert ketones or aldehydes to primary amines.
