4-溴甲基苯基硼酸 - Introduction
4-(Bromomethyl)phenylboronic acid, cyclic anhydride is an organic compound with a chemical formula of C7H7BrB(OH)2 and a molecular weight of 220.85. It is a white crystalline powder, soluble in many organic solvents such as ether and chloroform.
4-(Bromomethyl)phenylboronic acid, cyclic anhydride can be used in organic synthesis reactions, especially as a substitution reagent for aromatic compounds. It can participate in the coupling reaction of C- C and C- X bond formation, and is commonly used in the palladium-catalyzed Suzuki coupling reaction. In addition, it can also be used to synthesize organic semiconductor materials and other functional molecular compounds.
The method for preparing 4-(Bromomethyl)phenylboronic acid, cyclic anhydride is usually obtained by reacting bromoalkane and phenylboronic acid. For example, 4-bromomethylbenzene and triphenylphosphine palladium (II) chloride can be used as a catalyst to react with phenylboronic acid in the presence of a base.
Regarding safety information, 4-(Bromomethyl)phenylboronic acid, the physical and chemical properties of cyclic anhydride make it irritating and corrosive to skin, eyes and respiratory tract. Care should be taken when handling and using protective measures such as gloves, goggles and respiratory protective equipment. In addition, it is also a combustion substance and should avoid coexistence with oxidants and combustibles.
