VerwendenLithium 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 LixTiyOz thin films. Further, it is used in conjunction with organometallic reagents/catalysts to modify their reactivity and selectivity.
