Bis(pinacolato)diboron, CAS 73183-34-3 is a widely used reagent in organic synthesis, it has the ability bility to serve as a convenient source of boron in various chemical transformations. One prominent applications of Bis(pinacolato)diboron is in cross-coupling reactions, particularly in Suzuki-Miyaura coupling. In this reaction, it acts as a boron source, reacting with aryl halides or pseudohalides in the presence of a palladium catalyst to form biaryl compounds.
