双三甲基硅基胺基锂又叫六甲基二硅基氨基锂 (LiHMDS)。 双三甲基硅基胺基锂可用于制备低配位数的金属配合物,因为配体 (TMS)2N-的位阻很大。 这样的例子有M [N (TMS)2]3(M=Sc,Ti,V,Fe;TMS= (CH3)3Si))。 与三甲基氯硅烷反应产生三 (三甲基硅基)胺,其中氮的配位数为3,空间构型为平面正三角形。 在有机合成或药物合成中,双三甲基硅基胺基 …
Lithium bis(trimethylsilyl)amide 1.0M tetrahydrofuran 4039-32-1
Lithium bis(trimethylsilyl)amide (LHMDS) is a non-nucleophilic strong base widely used in organic synthesis for deprotonation reactions and base-catalyzed reactions. It is generally soluble in most nonpolar organic solvents.
