Description

General description

Lithium aluminum anhydride is effective as a selective reducing agent.The anhydride may be prepared by reacting lithium hydride with aluminum chloride. It is soluble in ether and it can reduce carboxyl group to primary alcohol group with great ease. Other organic compounds that can be reduced by lithium aluminum hydride are aldehydes, ketones, acid chlorides, acid anhydrides, halides, quinones, nitrogen compounds.
