General description

Sodium borohydride, also known as sodium tetrahydridoborate, is a highly basic boron hydride that is commonly used as a reducing agent. It reacts very slowly with water and acts as a catalyst and stabilizer.

Application

Sodium borohydride can be used as a reducing agent for the:
  • Synthesis of cobalt (II, III) oxide (Co3O4) from cobalt chloride (CoCl2) via a co-reduction process.
  • Solvent-free reduction of aldehydes and ketones to alcohols in the presence of solid acid as an activator.
  • Reductive amination of carbonyl compounds to secondary amines in the presence of silica-gel-supported sulfuric acid as a catalyst.
  • Raney nickel-catalyzed reduction of aromatic nitro compounds to aromatic amines.
