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.
