Bis[(-)-pinanediolato]diboron（Cat No.:L041866）is a chiral organoboron compound widely used in enantioselective synthesis and borylation reactions. It features two pinanediolato ligands coordinated to a diboron core, providing both steric bulk and chirality. This reagent is especially valuable in asymmetric Suzuki-Miyaura and other cross-coupling reactions, where it introduces boron-containing groups with high enantioselectivity. Its crystalline solid form offers good stability and ease of handling. Due to its unique combination of reactivity and chiral induction, it plays a crucial role in synthesizing complex, optically active molecules in pharmaceuticals and fine chemicals.
