Lithium bis(trimethylsilyl)amide, 20% (ca 1.06M) soln. in THF/ethylbenzene, packaged in resealable septum cap bottle
化学性质
应用
Lithium bis(trimethylsilyl)amide is used in generating enolates for preparing lactone precursors, pyranones, and cyclohexanes. It is used to catalyze the addition of phosphine P-H bonds to carbodiimides leading to phosphaguanidines and in a novel three-step synthesis of disubstituted 1,2,5-thiadiazoles. It is also used in the lithiation of ethyl acetate and in the stereospecific Wadsworth-Emmons synthesis of fluoroalkenes from (E)- and (Z)-fluorovinyl sulfones.
