LiHMDS is often used in organic chemistry as a strong non-nucleophilic base. [3] Its conjugate acid has a pK a of ~26, [4] making it is less basic than other lithium bases, such as LDA (pK a of conjugate acid ~36).
Lithium, sodium, and potassium bis(trimethylsilyl)amides are commercially available. When free of solvent, the lithium [5] and sodium [6] complexes are trimeric, and ...
Lithium amide or lithium azanide is an inorganic compound with the chemical formula LiNH 2. It is a white solid with a tetragonal crystal structure. [1] Lithium amide can be made by treating lithium metal with liquid ammonia: [2] 2 Li + 2 NH 3 → 2 LiNH 2 + H 2. Lithium amide decomposes into ammonia and lithium imide upon heating. [3]
Metal amides (systematic name metal azanides) are a class of coordination compounds composed of a metal center with amide ligands of the form NR 2 −. Amido complexes of the parent amido ligand NH 2 − are rare compared to complexes with diorganylamido ligand, such as dimethylamido.
The halide acts as a leaving group and ends up in solution. A workup step follows to remove any excess base within the solution. The overall reaction scheme is as follows: ROH + NEt 3 → RO − + H−NEt + 3; RO − + Cl−SiMe 3 → RO−SiMe 3 + Cl −; Bis(trimethylsilyl)acetamide, a popular reagent for silylation

Bis(trimethylsilyl)acetamide (BSA) is an organosilicon compound with the formula MeC(OSiMe 3)NSiMe 3 (Me = CH 3). It is a colorless liquid that is soluble in diverse organic solvents, but reacts rapidly with moisture and solvents containing OH and NH groups .
NaHMDS is used as a strong base in organic synthesis.Typical reactions: To deprotonate ketones and esters to generate enolate derivatives. [3]Generate carbenes by dehydrohalogenation of halocarbons.
