Solution structures are either solvated monomers or dimers (or mixtures thereof) with this depending on the coordinating power, concentration, and temperature of the solvent. [3] In general, weakly coordinating solvents such as toluene and N,N-dimethylethylamine give dimers, where as THF and diglyme gave monomers at high dilution. [ 3 ]
Lithium, sodium, and potassium bis(trimethylsilyl)amides are commercially available. When free of solvent, the lithium [5] and sodium [6] complexes are trimeric, and ...
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.
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.
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. Amide ligands have two electron pairs available for bonding.
