Lithium hydride - Wikipedia

Lithium aluminium hydride, commonly abbreviated to LAH, is an inorganic compound with the chemical formula Li[AlH4] or LiAlH4. It is a white solid, discovered by Finholt, Bond and Schlesinger in 1947. This compound is used as a reducing agent in organic synthesis, especially for the reduction of esters, carboxylic acids, and amides. The solid is dangerously reactive toward water, releasing gaseous hydrogen (H2). Some related derivatives have been discussed for hydr… Web1 jul. 2024 · Lithium aluminum hydride (LiAlH 4) is a pyrophoric chemical that is commonly used as a potent reducing agent in organic synthesis. (1) A synthetic organic chemistry research laboratory usually ordered powdered lithium aluminum hydride (LiAlH 4) but inadvertently ordered LiAlH 4 pellets instead. WebCarboxylic acids can be converted to 1 o alcohols using Lithium aluminum hydride (LiAlH 4 ). Note that NaBH 4 is not strong enough to convert carboxylic acids or esters to alcohols. An aldehyde is produced as an intermediate during this reaction, but it cannot be isolated because it is more reactive than the original carboxylic acid. great food truck race battle for the south
