Lithium bis(trimethylsilyl)amide (LiHMDS) is a sterically hindered strong base. It is commercially available as a solid and as a solution in a variety of solvents (ex. THF , 2Me-THF , toluene , hexane , and MTBE ).

Base employed in generating enolates for the preparation of lactone precursors, pyranones, and cyclohexanes. Used to catalyze the addition of phosphine P-H bonds to carbodiimides leading to phosphaguanidines. Also used in a novel three-step synthesis of disubstituted 1,2,5-thiadiazoles.

Lithiumbis(trimethylsilyl)amid ist ein farbloser Feststoff, der sich an Luft zersetzt, wobei Selbstentzündung erfolgen kann. Unter Stickstoff ist er beständig. [3] Als Feststoff liegt er als Trimer vor.

2025年2月6日 · In this work, the simple catalyst lithium bis(trimethylsilyl)amide (LiHMDS) with high activity was explored in detail for the synthesis of polylactide (PLA). Using LiHMDS as the catalyst, various cyclic esters were polymerized to obtain diverse sustainable polyesters, such as poly(lactide), poly(δ-valerolactone), and poly(caprolactone), with ...

2022年11月15日 · The LiHMDS acts as a scavenger for hydrofluoric acid and water and facilitates the formation of an (electro)chemical robust cathode|electrolyte interphase (CEI).
