Application
硼氢化钾（KBH4）可用作合成以下物质的还原剂：
它也可以用作镍-硼合金中的硼源，该合金可电沉积在碳纤维上以改善碳的催化石墨化作用。
- 通过还原铜盐制备铜纳米粒子。
- 在手性N，N′-二氧基钪（III）复合物催化剂存在下，通过烯酮和酮还原制备对映选择性烯丙醇。
- 在相转移催化剂PEG-400的存在下，通过还原硝基芳烃来制备乙氧基苯。

The first catalytic enantioselective 1,2-reduction of enones with 0.45 mol equiv potassium borohydride solution catalyzed by a chiral N,N'-dioxide-Sc(III) complex catalyst was accomplished under mild reaction conditions. A number of optically active allylic alcohols were obtained in good to excellent
