Borane - Wikipedia

Molecular BH3 is believed to be a reaction intermediate in the pyrolysis of diborane to produce higher boranes: B2H6 ⇌ 2BH3 BH3 +B2H6 → B3H7 +H2 (rate determining step) BH3 + B3H7 ⇌ B4H10 B2H6 + B3H7 → BH3 + B4H10 ⇌ B5H11 + H2 Further steps give rise to successively higher boranes, with B10H14 as the most stable end pro… Webto a primary amine.

WebBorane dimethylsulfide is one of the most common bulk reducing agents used in the Corey–Itsuno reduction. The dimethylsulfide ligand attenuates the reactivity of the borane. Activation by the nitrogen of the chiral oxazaborolidine catalyst of the stoichiometric reducing agent allows for asymmetric control of the reagent.
