A Zwitterionic Palladium(II) Complex as a Precatalyst for Neat-Water-Mediated Cross-Coupling Reactions of Heteroaryl, Benzyl, and Aryl Acid Chlorides with Organoboron Reagents
A zwitterionic palladium(II) complex has been found to be an efficient catalyst for Suzuki–Miyaura cross‐coupling reactions of aryl and heteroaryl organoboron reagents with various heteroaryl chlorides, aryl‐ and heteroarylmethyl chlorides, and aryl acid chlorides in neat water.

An efficient catalytic system for the ligand-free SuzukiâMiyaura reaction in water at room temperature is disclosed, promoted by Stilbazo (stilbene-4,4â²-bis[(1-azo)-3,4-dihydroxybenzene]-2,2â²-disulfonic acid diammonium salt). The desired carbonâcarbon bond formation proceeded well under mild conditions with high efficiency and good functional group tolerance.
