Suzuki Coupling Catalyzed by Ligand-Free Palladium(II) Species at Room Temperature and by Exposure to Air

Abstract

Ligand-free palladium acetate and palladium chloride have been evaluated as catalysts in the Suzuki cross-coupling of aryl boronic acid with aryl and vinyl bromide in ethanol at room temperature and with exposure to air. The substrates with a wide variety of functional groups, including base-sensitive ones are tolerated.

Key words

Suzuki coupling - palladium - catalysis
