Description

Bis(pinacolato)diboron or (B2pin2) is the most commonly used diborane reagent in organic synthesis due to its high stability in air and moisture. It can be synthesized by treating tetrakis(dimethylamino)diboron with pinacol in acidic conditions.Reagent used for the cis-vicinal diborylation of acetylenes and olefins with Pt catalysis; borylation of aromatics by Pd catalysis.
