This colourless solid is used in organic chemistry as a hydroboration reagent. The compound exists as a hydride-bridged dimer, which easily cleaves in the presence of reducible substrates. The compound is commercially available as a solution in tetrahydrofuran and as a solid. Its highly regioselective addition on alkenes allows the preparation of terminal alcohols by subsequent oxidative cleavage with H 2 O 2 in aqueous KOH. The steric demand of 9-BBN greatly suppresses the formation of the 2-substituted isomer compared to the use of borane. Contents move to sidebar hide.

The hydroboration-oxidation of alkynes is similar to the reaction with alkenes. However, there is one important difference. The alkyne has two pi bonds and both are capable of reacting with borane BH 3.
