Lithium tert-butoxide, 99.9% (metals basis), Thermo Scientific Chemicals

Lithium tert-butoxide is a mild base used in organic synthesis. It is involved in the alfa-alkylation reaction of ketones with primary alcohols. It is utilized as a catalyst in the reduction of ketones to the corresponding secondary alcohols. It acts as lithium source utilized in the preparation of Li_xTi_yO_z thin films. Further, it is used in conjunction with organometallic reagents/catalysts to modify their reactivity and selectivity.
