ナトリウムビス (トリメチルシリル)アミド 1M in THF

Lithium bis(trimethylsilyl)amide is a lithiated organosilicon compound with the formula LiN(Si(CH3)3)2. It is commonly abbreviated as LiHMDS or Li(HMDS) (lithium hexamethyldisilazide - a reference to its conjugate acid HMDS) and is primarily used as a strong non-nucleophilic base and as a ligand. Like many lithium reagents, it has a tendency to aggregate and will form a cyclic trimer in t… Web化学物質「lhmds」の詳細情報です。j-global 科学技術総合リンクセンターは研究者、文献、特許などの情報をつなぐことで、異分野の知や意外な発見などを支援する新しいサービスです。またjst内外の良質なコンテンツへ案内いたします。 WebLithium bis (trimethylsilyl)amide solution (1.0 M in THF) can be used as a base in directed aldol condensations and Darzens condensation reactions; α-arylation of aryl ester … corrugated trough
