Bis(catecholato)diboron is widely used in organic synthesis, particularly in the formation of carbon-boron bonds. It serves as a key reagent in Suzuki-Miyaura cross-coupling reactions, enabling the synthesis of biaryl compounds, which are essential in pharmaceuticals and materials science. Additionally, it is employed in the borylation of aromatic hydrocarbons, facilitating the introduction of boron groups into organic molecules. This compound is also utilized in the preparation of boron-containing polymers and advanced materials, contributing to the development of new technologies in electronics and optics. Its role in catalytic processes further enhances its importance in industrial and academic research.
