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.[1] The potential of NaBH4 to store as well as generate hydrogen for fuel cells has been investigated.[2][3]
• Application: Sodium borohydride can be used as a reducing agent:         To prepare saturated alcohols by the reduction of conjugated aldehydes and ketones.[4]         Along with Raney nickel for the reduction of aromatic nitro compounds to arylamines.[5]         In the synthesis of secondary amines by reductive amination of ketones and aldehydes in the presence of an acid catalyst.[6]        In the synthesis of δ and γ lactones by the reduction of cyclic anhydrides.[7]        For the chemoselective reduction of N -protected amino acids and peptides to corresponding alcohols.[8]
