摘要：

The palladium-catalyzed arylation of ethylene under aqueous or aqueous-organic solvent two-phase conditions has been studied using PdCl(2)L(2) (L, phosphorus ligand) as the catalyst. Both aqueous NaHCO3-soluble and -insoluble bromoarenes possessing electron withdrawing groups react with ethylene to give the styrenes in,oood yields by water-soluble catalyst (L, (C6H5)(2)P(m-C6H4SO3Na (tppms) (1). Bromoarenes possessing electron-donating groups react with difficulty but the reaction takes place with the corresponding iodoarenes to afford the products in moderate yields. The reaction of 3-bromobenzoic acid by water-insoluble (L, (C6H5)(3)P (tpp) (2) under two-phase conditions gave the product in a poor yield.
