4-Chlorobenzeneboronic acid, 98+%
Description
Used as a GC reagent for diols. It is a reagent used for palladium-catalyzed direct arylation, cyclopalladation, tandem-type Pd(II)-catalyzed oxidative Heck reaction and intramolecular C-H amidation, copper-mediated ligandless aerobic fluoroalkylation, Pd-catalyzed arylative cyclization, ruthenium catalyzed direct arylation, ligand-free copper-catalyzed coupling reactions and regioselective arylation and alkynylation by Suzuki-Miyaura and Sonogashira cross-coupling reactions. Also in as a reagent in the preparation of catalysts for Suzuki-Miyaura cross-coupling, palladium(II) thiocarboxamide complexes as Suzuki coupling catalysts, Biaryls by Suzuki reactions of aryl chlorides, bromides, and iodides with arylboronic acids.
