1907-33-1 - Application:

Lithium tert-Butoxide (LiOtBu) (CAS: 1907-33-1), decomposed by water absorption, soluble in organic solvents such as toluene, hexane and tetrahydrofuran.
Lithium tert-Butoxide is one of the organometallic compound. Used in organic synthesis to change the activity and selectivity of catalysts in organometallic polymerization reactions.
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 LixTiyOz thin films. Further, it is used in conjunction with organometallic reagents/catalysts to modify their reactivity and selectivity.
