Also known as (+)-Diisopinocampheylborane, Bis[(1S,2R,3S,5S)-2,6,6-trimethylbicyclo[3.1.1]hept-3-yl]borane
Diisopinocampheylborane is an organoborane that is useful for asymmetric synthesis. This colourless solid is the precursor to a range of related reagents. The compound was reported in 1961 by Zweifel and Brown in a pioneering demonstration of asymmetric synthesis using boranes. The reagent is mainly used for the synthesis of chiral secondary alcohols. The reagent is often depicted as a monomer but like most hydroboranes, it is dimeric with B-H-B bridges.

==Preparation== Diisopinocampheylborane was originally prepared by hydroboration of excess α-pinene with borane, but it is now more commonly generated from borane-methyl sulfide (BMS).
