A highly versatile synthesis of amine-boranes via carbonyl reduction by sodium borohydride is described. Unlike the prior bicarbonate-mediated protocol, which proceeds via a salt metathesis reaction, the carbon dioxide-mediated synthesis...

Abstract Sodium borohydride reacts with sulfur in ammonia, primary, secondary or tertiary amines with hydrogen evolution to give the corresponding amine boranes, R3-nHnN-BH3. The reaction of sodium borohydride with carbon disulfide in the presence of a tertiary amine yields compounds R3N-BH3. The formulation of these reactions has been established by 11B and 1H NMR.
