Hydroxyborohydride (sodium and potassium salts) were prepared by a one-pot method and the 1H NMR spectrum of sodium hydroxyborohydride was recorded for the first time. Based on an NMR experiment, hydroxyborohydride was found to be more reactive toward acetone carbonyl than borohydride. The calculated 11B- and 10B–H coupling constants are in very good agreement with experimental data, and support the hypothesis about the detection of the (BH3OH)− anion as an individual species in solution.
The presented high yield synthetic route providing hydroxyborohydride salts is fast and economic, making hydroxyborohydrides quite attractive reagents. The first 1H NMR spectrum of hydroxyborohydride shows a very unusual pattern of resonances from heteronuclear coupling of boron-hydride moiety. The calculated 11B- and 10B–H coupling constants are in very good agreement with experimental data, and confirm the hypothesis about the detection of the (BH3OH)− anion as an individual species in solution.Figure optionsDownload as PowerPoint slide
