Borane-tetrahydrofuran complex, 1M soln. in THF, stab. with 5mmol NaBH4


Chemical Properties

Formula Weight
Flash Point
Air & Moisture Sensitive
Miscible and reacts violently with water.


Borane-tetrahydrofuran complex 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. It is utilized to reduce nylon surface amide groups to secondary amines.


Air and moisture sensitive. Forms explosive peroxides in contact with air. Incompatible with acids, acid chlorides, acid anhydrides, oxidizing agents and alcohols. On hydrolysis, it forms hydrogen and boric acid.

GHS Hazard and Precautionary Statements

Hazard Statements: H225-H260-H302-H333-H315-H318-H351-H335

Highly flammable liquid and vapour. In contact with water releases flammable gases which may ignite spontaneously. Harmful if swallowed. May be harmful if inhaled. Causes skin irritation. Causes serious eye damage. Suspected of causing cancer. May cause respiratory irritation.

Precautionary Statements: P223-P210-P303+P361+P353-P305+P351+P338-P405-P501a

Keep away from any possible contact with water, because of violent reaction and possible flash fire. Keep away from heat/sparks/open flames/hot surfaces. - No smoking. IF ON SKIN (or hair): Remove/Take off immediately all contaminated clothing. Rinse skin with water/shower. IF IN EYES: Rinse cautiously with water for several minutes. Remove contact lenses, if present and easy to do. Continue rinsing. Store locked up. Dispose of contents/container in accordance with local/regional/national/international regulations.
