WebYes, lithium aluminum hydride (LiAlH4) is more reactive than lithium hydride (LiH). LiAlH4 is a powerful reducing agent that is commonly used in the laboratory for the reduction of esters, carboxylic acids, and other functional groups. LiH is a less reactive compound and is not as commonly used in chemical reactions. Sponsored by TruthFinder 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.
