Beschreibung

Allgemeine Beschreibung

Lithium aluminum hydride (LiAlH₄) is a powerful reducing agent used in organic synthesis to reduce esters, carboxylic acids, acyl chlorides, aldehydes, epoxides, and ketones into the corresponding alcohols. It also converts amide, nitro, nitrile, imine, oxime, and azide compounds into amines.[1]

Anwendung

• Dehydrogenation studied with various catalysts[2]
• Regeneration of methoxysilanes via reduction[3]
• Transition metal electrophilic hydrogen activation via heterolytic cleavage[4]
• Formation of nickel hydrogenation catalysts[5]
• Hydrogen sorption[6]
• Electrodeposition of Al on W-Cu substrates[7]
