Allgemeine Beschreibung

Lithium borohydride, a white solid, may be prepared from the exchange reaction of LiCl and sodium borohydride in isopropylamine. The orthorhombic crystal structure converts to tetragonal at 108oC and eventually melting at 278oC. Infrared and Raman spectral studies at 80oC have been reported in a study.
We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product has been enhanced for energy efficiency. Find details here.

Anwendung

Versatile reducing agent for aldehydes, ketones, acid chlorides, lactones, epoxides, and esters. Applied in the lithiation of 2H-WS2 giving high yields of exfoliated WS2, and opening the way to new intercalation compounds and nanocomposites.

In the presence of large excesses of borohydride salts, gold monolayer protected-clusters can be grown to larger sizes simply by controlling the amount of reducing agent added to smaller clusters. In addition, gold monolayer clusters can be used as catalysts

For solid-phase peptide synthesis, 2,4-dimethoxy-4'-hydroxbenzhydrol linker was prepared via lithium borohydride reduction of 2,4-dimethoxy-4'-hydroxybenozophenone. The potassium salt of the linker was coupled to chloromethylpolystyrene. This method proved to be better than use of the cesium salt. This new synthesis gave

Complex Hydrides: A New Category of Solid-state Lithium Fast-ion Conductors

Research and development of solid-state lithium fast-ion conductors is crucial because they can be potentially used as solid electrolytes in all-solid-state batteries, which may solve the safety and energy-density related issues of conventional lithium-ion batteries that use liquid (farmable organic) electrolytes.
