摘要：

An X-ray diffraction study of PdCl 2(BPPFA) (BPPFA = racemic ( S *)- N,N-dimethyl-1-[( R *)-1′,2-bis(diphenylphosphino)ferrocenyl]ethylamine was carried out. The palladium-BPPFA complex has square-planar geometry with two cis chlorine and two phosphorus atoms, and the nitrogen atom which is not bound to palladium. The orientation of the four phenyl groups around the phosphorus atoms is nearly the same as that in its achiral analogue, PdCl 2(dppf) (dppf = 1,1′-bis(diphenylphosphino)ferrocene). The aminoalkyl side chain on the cyclopentadienyl ring is responsible for fixing the chiral conformation of the palladium-ferrocenylbisphosphine chelate.
