Description and Uses
Borane tetrahydrofuran complex (BH3-THF) is widely used as a reducing agent in organic synthesis. It is also used as a reagent in hydroboration reactions.It is a charge-transfer complex that is a useful surrogate for diborane1 in organic synthesis. It can be used to reduce carboxylic acids to alcohols or nitriles to primary amines. It reacts with olefins to add the BH2 functional group. Alkyl- or arylboranes formed in this way can further react with unsaturated compounds such as olefins, imines, ketones, and alkynes (the hydroboration reaction) to make useful boron-containing intermediates.
Borane-tetrahydrofuran complex is used to reduce Nylon surface amide groups to secondary amines.It is an important reagent used in the reduction of certain functional groups viz. aldehyde, ketone, carboxylic acid, amide, oxime, imine and nitrile. It is also used as hydro borating agent. It acts as a borane source for oxazaborolidine catalyzed asymmetric reductions.
