Description

CAS: 4039-32-1 | C6H18LiNSi2 | 167.327 g/mol

Lithium bis(trimetylsilyl)amide is used as a strong base in organic synthesis and as catalysts in polymerization reactions. It is also used to form various organolithium compounds such as acetylides and lithium enolates. It is a base employed in generating enolates for preparation of lactone precursors, pyranones and cyclohexanes. Further, it is used to catalyze the addition of phosphine P-H bonds to carbodiimides leading to phosphaguanidines. In addition, it is used in a three-step synthesis of disubstituted 1,2,5-thiadiazoles.

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.
