硼氢化锂是一种白色固体,可由氯化锂和硼氢化钠在异丙胺中的交换反应制备。正交晶体结构在 108 o C 转变为四方相,最终在 278 o C 熔化。已报道了一项红外和拉曼光谱在 80 o C 下的研究。

應用

用于醛、酮、酸性氯化物、内酯、环氧化物和酯的多功能还原剂。应用于 2H-WS 2 的锂化,获得了高收率的脱落 WS 2,为新的插层化合物和纳米复合材料开辟了道路。采用硼氢化锂作为贮氢系统。它在 320-380 o C 和 10 atm(H2 压力)下再生氢。

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

文章

An article about metal borohydrides as hydrogen storage materials

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.
