    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).

    en.wikipedia.org/wiki/Organolithium_reagent

    The structures of common lithium amides, such as lithium diisopropylamide (LDA) and lithium hexamethyldisilazide (LiHMDS) have been extensively studied by Collum and coworkers using NMR spectroscopy. [17] Another important class of reagents is silyllithiums, extensively used in the synthesis of organometallic complexes and polysilane dendrimers.

    en.wikipedia.org/.../Metal_bis(trimethylsilyl)amides

    Lithium, sodium, and potassium bis(trimethylsilyl)amides are commercially available. When free of solvent, the lithium [5] and sodium [6] complexes are trimeric, and ...

  5. Metal amides - Wikipedia

    en.wikipedia.org/wiki/Metal_amides

    The lithium amides are more common and more soluble than the other alkali metal analogs. Potassium amides are prepared by transmetallation of lithium amides with potassium t-butoxide (see also Schlosser base ) or by reaction of the amine with potassium , potassium hydride , n-butylpotassium , or benzylpotassium .

  6. Bis(trimethylsilyl)amine - Wikipedia

    en.wikipedia.org/wiki/Bis(trimethylsilyl)amine

    Bis(trimethylsilyl)amine (also known as hexamethyldisilazane and HMDS) is an organosilicon compound with the molecular formula [(CH 3) 3 Si] 2 NH. The molecule is a derivative of ammonia with trimethylsilyl groups in place of two hydrogen atoms.

  7. Silylation - Wikipedia

    en.wikipedia.org/wiki/Silylation

    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
