4-Bromobenzeneboronic acid, 97+%
Description
4-Bromobenzeneboronic acid is a reagent used for Palladium catalyzed Suzuki-Miyaura cross-couplings, Tandem-type Pd(II)-catalyzed oxidative Heck reaction and intramolecular C-H amidation sequence. It is also used in the preparation of Protein modulators and enzymatic and kinase inhibitors, Gallate-based obovatol analogs with potential anti-tumor activity. It is used as a reagent for Copper-mediated ligandless aerobic fluoroalkylation of arylboronic acids with fluoroalkyl iodides, Pd-catalyzed arylative cyclization of alkyne-tethered enals or enones via carbopalladation of alkynes, Copper-catalyzed cross-couplings.
