Abstract	Mild conditions have been developed to achieve the Pd(OAc)2-catalyzed fluoride-free cross-coupling between thearyl bromides and arylsiloxanes in good to high yields inaqueous medium. The success of the reactions requires thepresence of poly(ethylene glycol) (PEG) and 3 equiv ofsodium hydroxide. The product was easily separated withethyl ether extraction, and the catalytic system can be reusedeight times with high efficiency.
