Web21 dec. 2024 · Uses. Lithium bis (trimethylsilyl)amide is a base used in preparation of dienes and enolates. It is used to catalyze the addition of phosphine P-H bonds to carbodiimides leading to phosphaguanidines. Lithium bis (trimethylsilyl)amide is also used in a novel three-step synthesis of disubstituted 1,2,5-thiadiazoles. WebSubstituted acrylamide derivatives of benzylamine are lithiated α to nitrogen by LDA. The benzyllithium thus formed undergoes either 5-endo-trig anionic cyclisation, formally by intramolecular conjugate addition to the acrylamide, to yield 5-membered lactams, or, if the acrylamide bears a β-electron withdrawing group, 4-exo-trig cyclisation to a β-lactam. cinemark earnings https://colonialbapt.org
