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

applications

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
