應用

硼氢化钾(KBH4)可用作合成以下物质的还原剂:       
  • 通过还原铜盐制备铜纳米粒子。
  • 在手性NN′-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。

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。

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

Room-temperature ionic liquid in combination with sodium diethyldithiocarbamate (DDTC) was used to synergetically improve the chemical vapor generation (CVG) of nickel. Volatile species of nickel were effectively generated through reduction of acidified analyte solution with KBH(4) in the presence of
