Description

General description

Sodium borohydride (NaBH₄) is the most commonly available borohydride, synthesized by reacting methylborate with sodium hydride in mineral oil. It is employed as a precursor for producing other metal borohydrides. Various approaches for qualitative and quantitative monitoring of sodium borohydride have been explained. The potential of NaBH₄ to store as well as generate hydrogen for fuel cells has been investigated.

Application

Sodium borohydride can be used as a reducing agent:        

• To prepare saturated alcohols by the reduction of conjugated aldehydes and ketones.        
• Along with Raney nickel for the reduction of aromatic nitro compounds to arylamines.        
• In the synthesis of secondary amines by reductive amination of ketones and aldehydes in the presence of an acid catalyst.       
• In the synthesis of δ and γ lactones by the reduction of cyclic anhydrides.       
• For the chemoselective reduction of N -protected amino acids and peptides to corresponding alcohols.
