Hydrolysis of the Borohydride Anion BH₄⁻: A ¹¹B NMR Study Showing the Formation of Short-Living Reaction Intermediates including BH₃OH⁻

Molecules, 2022
In hydrolysis and electro-oxidation of the borohydride anion BH4−, key reactions in the field of energy, one critical short-living intermediate is BH3OH−. When water was used as both solvent and reactant, only BH3OH− is detected by 11B NMR.
