Lithium aluminium hydride (LiAlH4) - LAH - Txo-Mechanism. …LiAlH4 reagent tuaj yeem txo aldehydes rau thawj cawv, ketones rau cov cawv thib ob, carboxylic acids thiab esters rau thawj cawv, amides thiab nitriles rau amines, epoxides rau cawv thiab lactones rau diols.
Puas lah teb nrog amides?
Amides tuaj yeem hloov pauv rau 1°, 2° lossis 3° amines siv LiAlH4.
Can amides txo los ntawm LiAlH4?
Amides tuaj yeem txo rau amines los ntawm LiAlH 4: Nco ntsoov tias txo qis ntawm tag nrho lwm cov carboxylic acid derivatives muaj cov pab pawg carbonyl tsim cov cawv: Lwm qhov tshwj xeeb yog cov nitriles, tab sis cov no tsis muaj cov pab pawg carbonyl thiab nyob ntawm tus neeg sawv cev txo qis, cov khoom sib txawv tuaj yeem tau txais.
Dab tsi tuaj yeem txo amides?
Cov amides tuaj yeem txo qis nrog lithium aluminium hydride rau cov khoom siv Mannich sib raug.
lah tsis txo?
Lithium aluminium hydride tsis txo yooj yim alkenes lossis arenes. Alkynes tsuas yog txo yog tias ib pawg cawv nyob ze. Nws tau pom tias LiAlH4 txo qis ob daim ntawv cog lus hauv N-allylamides.
