Descrizione

Lithium bis(trimethylsilyl)amide is used in generating enolates for preparing lactone precursors, pyranones, and cyclohexanes. It is used to catalyze the addition of phosphine P-H bonds to carbodiimides leading to phosphaguanidines and in a novel three-step synthesis of disubstituted 1,2,5-thiadiazoles. It is also used in the lithiation of ethyl acetate and in the stereospecific Wadsworth-Emmons synthesis of fluoroalkenes from (E)- and (Z)-fluorovinyl sulfones. 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. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
