Polyphenyl derivatives Q 0700Aqueous Suzuki Coupling Reaction Catalyzed by Water-Soluble Diimine/Pd(II) Systems. -The Suzuki cross coupling reaction of aryl bromides (I) and chlorides (IV) with arylboronic acids (II) is catalyzed by arylsulfonate-containing diimine-Pd(II) complexes in DMA or aqueous solution. A wide range of substituents is tolerated, although the reaction is not effective for deactivated aryl chlorides [cf. (Vc)]. Catalyst loadings as low as 0.01 mol% can be applied in aqueous solution. -(ZHOU, J.; GUO, X.; TU, C.; LI, X.; SUN*, H.; J.
