Application
Potassium borohydride (KBH4) can be used as a reducing agent for the synthesis of:
It can also be employed as a boron source in the nickel–boron alloy, which is electrodeposited on carbon fiber to improve catalytic graphitization of carbon.
- Copper nanoparticles by the reduction of copper salts.
- Enantioselective allylic alcohols by the catalytic reduction of enones and ketones in the presence of chiral N,N′-dioxidescandium(III) complex catalyst.,·
- Azoxybenzenes by the reduction of nitroarenes in the presence of phase transfer catalyst PEG-400.
It can also be employed as a boron source in the nickel–boron alloy, which is electrodeposited on carbon fiber to improve catalytic graphitization of carbon.

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
