WebWARNING ON THE USE OF LITHIUM ALUMINIUM HYDRIDE (LAH) Powdered lithium aluminium hydride must never be allowed to come into contact with water. 1. All apparatus and reactants should be perfectly dry, and reactions should be run rigorously under nitrogen, with the reaction temperature below 70°C at all times. 2. Order of addition is important. 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.
