Abstract
Glyoxal bis(methylphenylhydrazone) 1 was prepared and examined as a ligand for the Suzuki-Miyaura cross-coupling reaction of aryl bromides and arylboronic acids. We found phosphine-free catalyst, such as Pd(OAc)2/hydrazone ligand 1 to be an efficient catalyst for a variety of substrates to produce the coupling products in good yields at room temperature.
Key words
hydrazone - Suzuki-Miyaura reaction - cross-coupling - palladium - phosphine-free
