摘要
Copper(I) complexes [Cu(CNR)(2)(kappa (2)-P,P-dppf)][BF4] (R = 'Bu (1), 2,6-Me2C6H3 (2), Cy (3), Bz (4)) containing the chelating dppf ligand (dppf = 1, 1'-bis(diphenylphosphino)ferrocene) have been prepared by reaction of the complex [Cu-2(mu -Cl)(2)(kappa (2)-P,P- dppf)(2)] with the corresponding isocyanide C equivalent to NR (molar ratio 1:1). Alternatively, complexes 1-4 can also be obtained by the reaction of the acetonitrile complexes [Cu(MeCN)(2)(kappa (2)-P,P-dppf)][BF4] with 2.5 equivalents of C equivalent to NR in refluxing dichloromethane. The crystal structures of [Cu-2(mu -Cl)(2)(kappa (2)-P,P-dppf)(2)] and [Cu(CN'Bu)(2)(kappa (2)-P,P-dppf)][BF4], determined by X-ray diffraction, are also reported. (C) 2001 Elsevier Science B.V.
