摘要：
A complete series of dppfMX(2) (M = Pt, Pd; X = Cl, Br, I) compounds have been synthesized using different routes, and characterized fully. The synthesis of dppfPdI, has been achieved by reacting Pd(COD)Cl-2 with dppf in the presence of NaI. X-ray structures of dppfPdBr(2) and dppfPdI(2) have also been reported for the first time in this study. A preliminary Suzuki coupling screening study reveals that dppfPdX(2), compounds are superior to the conventional Ph3P-based catalysts and bidentate phosphine-based ligands. Reactions carried out under in situ conditions also gave a similar trend, but their respective activities were much lower than that of the fully formed catalysts. (C) 2001 Elsevier Science B.V.
