摘要：

The complex [Rh(COD)(dppf)]ClO4 (COD = 1,5-cyclooctadiene; dppf = Fe((eta-5-C5H4)P(C6H5)2)2) has been prepared by removal of the chloride ligand from [RhCl(COD)]2 by AgClO4 in acetone, followed by addition of one equivalent of 1,1'-bis(diphenylphosphino)ferrocene. Reaction of [Rh(COD)(dppf)]ClO4 with dihydrogen in the presence of NaBPh4 affords the neutral complex [Rh(dppf)(eta-6-C6H5)B(C6H5)3], which has been characterized by single crystal X-ray analysis. The Rh(dppf)+ ion interacts strongly with the tetraphenylborate anion, one of the C6H5 groups being eta-6-coordinated to the metal. The plane defined by the two P atoms of the chelated bisphosphine and the Rh atom is almost perpendicular to the mean plane containing the eta-6-bonded phenyl group. The H-1 and P-31 NMR spectra of the isolated complexes are also discussed.
