WebSodium borohydride (or sodium borodeuteride) is also used to convert aldoses or oligosacchrides to alditol derivatives for examination by gas–liquid chromatography–mass spectrometry. Unlike hydride ions, which are electron-rich nucleophiles, diborane is the dimer of an electron-deficient electrophilic species (BH3 ).
