Sodium borohydride - Wikipedi

Le tétrahydruroborate de sodium, aussi appelé borohydrure de sodium, est un composé chimique constitué d'atomes de bore, de sodium et d' hydrogène. Sa formule brute est NaBH 4. C'est un agent réducteur utilisé notamment dans l'industrie pharmaceutique en tant que source d' hydrures H - L'aluminohydrure de lithium, aussi appelé tétrahydruroaluminate de lithium (LiAlH 4), généralement noté LAH, est un puissant générateur d'hydrures donc un fort réducteur utilisé en chimie organique.Il est plus puissant que le borohydrure de sodium (appelé aussi tétrahydruroborate de sodium), autre réactif de réduction, car la liaison Al-H est plus faible que la liaison B-H.

The most common hydride reducing agents are the lithium aluminum hydride (LiALH4) also abbreviated as LAH and sodium borohydride (NaBH4): The principle behind the hydride reducing agents is the presence of a polar covalent bond between a metal and hydrogen

  1. The key difference between LiAlH4 and NaBH4 is that LiAlH4 can reduce esters, amides and carboxylic acids whereas NaBH4 cannot reduce them.. Both LiAlH4 and NaBH4 are reducing agents. But LiAlH4 is a very strong reducing agent than NaBH4 because the Al-H bond in the LiAlH4 is weaker than the B-H bond in NaBH4

NaBH4 is also occasionally used for reductive aminations. NaBH4 is usually used in hydroxylic solvents such as MeOH, EtOH, and H2O. Sometimes THF is used as a solvent, either alone or as a solvent mixture (ex. THF/MeOH or THF/EtOH). In MeOH and EtOH, NaBH4 decomposes over time to give the respective borates. An excess of NaBH4 can be used to compensate for the decomposition of the reagent over.

NaBH4 réagit très violemment avec l'eau pour donner de l'hydrogène (entre autres), et plus cela peut exploser. Alors acide ou basique si tu as de l'eau dons ton milieu... NaBH4 + 2 H2O --> NaBO2 + 4 H2. Il est également instable en milieu oxydant... forcément! 0 0 1. Connectez-vous pour commenter des réponses Publier; grosbenji . il y a 1 décennie.

Abstract. We deposited monolayer films of shaped Ag nanoparticles on optical substrates using a simple low-temperature wet-chemical route. We add silver nitrate and sodium borohydride as reducing. Lithium aluminium hydride, commonly abbreviated to LAH, is an inorganic compound with the chemical formula Li Al H 4.It was 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 (H 2) NaBH4 + H2O = NaBO2*4H2O + H2 - Pengimbang Persamaan Kimia.
