Application

This lithium borate complex is widely used as a key intermediate in Suzuki-Miyaura cross-coupling reactions, enabling the synthesis of biaryl compounds for pharmaceuticals and agrochemicals. Its sterically hindered dioxaborolane structure enhances stability and reactivity in polymerization catalysts, particularly for olefin and styrene derivatives. Researchers also employ it as a ligand precursor in asymmetric catalysis and as a boron source for advanced electrolyte formulations in lithium-ion batteries.
