Used for preparation of anhydrous Li salts of carboxylic acids prior to reaction with organothium reagents (most often methyl or phenyl) as a useful route to ketones. Also used in the preparation of LiCN by reaction with acetone cyanohydrins. It is also applied as a desiccating and condensing agent and a shielding material in nuclear energy production. It is used in the manufacture of catalysts for polyolefin plastics; in fuels for aircraft, missiles. It is used in metallurgy, as degasifier, deoxidizer, desulfurizer; as grain refiner in non-ferrous metals. Employed as a chemical intermediate for butyllithium polymerization catalyst; in alloys with aluminum or magnesium for aerospace uses.

Used for preparation of anhydrous Li salts of carboxylic acids prior to reaction with organothium reagents (most often methyl or phenyl) as a useful route to ketones. For a comprehensive review of this method, see: Org. React., 18, 1 (1970). For an example (cyclohexyl methyl ketone), see: Org. Synth. Coll., 5, 775 (1973).
For preparation of LiCN by reaction with acetone cyanohydrin, see: Org. Synth. Coll., 7, 517 (1990).
A procedure for activation involves treatment with TMS chloride and a catalytic amount of Zn or a Zn salt. This reagent will reduce a ketone to the TMS ether of the alcohol: J. Org. Chem., 59, 217 (1994).
