    Diborane

    The simplest boron hydride known is diborane. B2H6 is prepared by the following methods:

    • Laboratory Method: In the laboratory, it is prepared by the reaction of sodium borohydride with iodine in a high boiling polyether solvent(CH3OCH2CH2)2O.
      2 \mathrm{NaBH}_{4}\: +\: \mathrm{I}_{2} \stackrel{\text { Polyether }}{\longrightarrow} \mathrm{B}_{2} \mathrm{H}_{6}\: +\: 2 \mathrm{NaI}\: +\: \mathrm{H}_{2}
    • Industrial Method: 
      2 \mathrm{BF}_{3}\: +\: 6 \mathrm{LiH} \stackrel{450 \mathrm{K}}{\longrightarrow} \mathrm{B}_{2} \mathrm{H}_{6}+\mathrm{LiF}
    • From Boron Halides:
      4 \mathrm{BX}_{3}+3 \mathrm{LiAlH_{4}}\: \rightarrow 2 \mathrm{B}_{2} \mathrm{II}_{6}+3 \mathrm{LiX}+3 \mathrm{AlX}_{3}
    • When boron halides and excess of hydrogen undergo reaction by passing silent electric discharge at low pressure, B2H6 is formed.
