Boronic acids and boronate esters are commonly used reagents in Suzuki–Miyaura coupling chemistry. Organoboron derivatives are common reagents for C–C bond formation, either through classical palladium-mediated transformations or through other newer coupling methods. Boronic esters and acids are potential intermediates in the manufacture of many active pharmaceutical ingredients (API).
Benzene is an important organic compound with the chemical formula C6H6, and its molecule consists of a ring of 6 carbon atoms, each with 1 hydrogen atom. Benzene is a sweet, flammable, colorless and transparent liquid with carcinogenic toxicity at room temperature, and has a strong aromatic odor. It is insoluble in water, easily soluble in organic solvents, and can also be used as an organic solvent itself. The ring system of benzene is called benzene ring, and the structure after removing one hydrogen atom from the benzene ring is called phenyl. Benzene is one of the most important basic organic chemical raw materials. Many important chemical intermediates can be derived from benzene through substitution reaction, addition reaction and benzene ring cleavage reaction.
