Pinacolborane (Cat No.:R048507) is an organoboron compound widely used in organic synthesis, particularly in hydroboration reactions. It consists of a boron atom bonded to a hydrogen and a pinacol-derived diol ligand, forming a stable, air-sensitive liquid with the formula C₆H₁₃BO₂. Pinacolborane is valued for its mild reactivity, regioselectivity, and compatibility with various functional groups, making it ideal for the selective hydroboration of alkenes and alkynes. It is also used in borylation reactions to install boron-containing groups for further functionalization in cross-coupling reactions, especially in the synthesis of pharmaceuticals and fine chemicals.
