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.
This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
