LiAlH4 is a strong, unselective reducing agent for polar double bonds, most easily thought of as a source of H-. It will reduce aldehydes, ketones, esters, carboxylic acid chlorides, carboxylic acids and even carboxylate salts to alcohols. Amides and nitriles are reduced to amines.
How does LiAlH4 reduce ketones?
The reaction of LiAlH4 with aldehydes and ketones involves the nucleophilic reaction of hydride (delivered from _AlH4) at the car- bonyl carbon. The lithium ion acts as a Lewis acid catalyst by coordinating to the carbonyl oxygen. … 19.22, all four hydrides of LiAlH4 are active in the reduction.
How does LiAlH4 reduce esters?
Ch20: Reduction of Esters using LiAlH4 to 1o alcohols. Carboxylic esters are reduced give 2 alcohols, one from the alcohol portion of the ester and a 1o alcohol from the reduction of the carboxylate portion. Esters are less reactive towards Nu than aldehydes or ketones.
