BIS(PINACOLATO)DIBORON, 99% is supplied by Merck (Sigma-Aldrich). It is mostly utilized diborane reagent in organic synthesis due to its high stability in air and moisture.

It is utilized:

-for the cis-vicinal diborylation of acetylenes and olefins with Pt catalysis; borylation of aromatics by Pd catalysis

-as a substrate in a new palladium-catalyzed cyclization of 1,6-enynes leading to homoallylic alkylboronates

-to construct a tetramethylpyrrolidine nitroxide scaffold for the synthesis of paramagnetic heterocycles by Suzuki coupling
