摘要

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.
