Bis(pinacolato)diboron Chemical Properties,Uses,Production

Chemical Properties

Bis(pinacolato)diboron is a white crystal powder, It is commonly used coupling reagent.

Uses

Bis(pinacolato)diboron is used as a condensation agent in the preparation poly(arylene)s. Bis(pinacolato)diboron is an organoboranate with potential use as matrix metallo-proteinase (MMP-2) inhibitor.

General 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.
