WebAug 12, 2024 · Diborane is produced on an industrial scale by the reaction of BF3 with sodium hydride. 2BF 3 + 6NaH + (Heat, 450 K) → B 2 H 6 + 6NaF. Diborane is a colorless, highly toxic gas with a b.p. of 180 K. Diborane catches fire spontaneously upon exposure to air. It burns in oxygen releasing an enormous amount of energy. WebII.B.6.b Borohydrides and diborane. In contrast to lithium aluminum hydride, sodium borohydride and lithium borohydride are relatively stable in water and can be used to reduce lactones to sugars in acid media or to the alditol in basic media. Thus, at pH 5, D-glucono-1,5-lactone affords D-glucose and, at pH 9, D-glucitol.
