Lialh4 with carboxylic acid
Web2. Lithium aluminium hydride is used to reduce carboxylic acids, esters, and acid halides to their corresponding primary alcohols. For example, LiAlH 4 reduction of acetic acid, methyl acetate, and acetyl chloride yield the same ethyl alcohol. 3. Lithium aluminium hydride, LiAlH 4, reduces the amides to amines. This method is particularly ... WebCarboxylic acids react with Thionyl Chloride ( SOCl 2) to form acid chlorides. During the reaction the hydroxyl group of the carboxylic acid is converted to a chlorosulfite …
