Lithium tert-butoxide, 99%, Thermo Scientific Chemicals

Description

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.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand.
