Abstract: Diborane is produced by reacting lithium or sodium borohydride with boron trifluoride in the absence of a solvent, thereby avoiding the dangers associated with the ether solvents previously used in similar reactions. The reaction appears to proceed via hydride abstraction from the borohydride, rather than via the hydride-halide exchange mechanism in the corresponding reaction in ether solution. Yields of about 95% can be achieved.

Abstract translation: 在不存在溶剂的情况下，通过使硼氢化锂或硼氢化钠与三氟化硼反应来制备二硼烷，从而避免与以前在类似反应中使用的醚溶剂相关的危险。 该反应似乎是通过氢化物从硼氢化物取代进行的，而不是通过在醚溶液中的相应反应中的氢化物 - 卤化物交换机理。 可获得约95％的产率。
