Anwendungen

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.

Bemerkungen

Store away from oxidizing agents. Keep the container tightly closed and place it in a cool, dry and well ventilated condition.
