  Palladium(II)-induced preferential activation of the σ[C_sp2(phenyl)–Cl] bond versusσ[C_sp2(ferrocene)–H]. Crystal structure of [Fe(η⁵-C₅H₅){η⁵-C₅H₄CH₂NCH(C₆H₃Cl₂-2,6)}]

  摘要：

  The ferrocenylimine [Fe(eta(5)-C5H5){eta(5)-C5H4CH2N=CH(C6H3Cl2-2,6)}] has been prepared by condensation of aminomethylferrocene and 2,6-dichlorobenzaldehyde, and characterized by IR, NMR (H-1 and C-13) spectroscopy and X-ray diffraction. The compound is triclinic, space group P (1) over bar, with a = 7.553(3), b = 11.763(2), c = 18.148(2) Angstrom, alpha = 89.94(1), beta = 98.90(2) and gamma = 91.91(2)degrees. It reacts with Na-2[PdCl4] and NaO2CMe . 3H(2)O in a 1:1:1 molar ratio, producing the di-mu-chloro-bridged cyclopalladated complex [{Pd[(3-ClC6H3)CH=NCH2(eta(5)-C5H4)Fe(eta(5)-C5H5)](mu-Cl)}(2)]. Further treatment of this compound with triphenylphosphine results in cleavage of the 'Pd(mu-Cl)(2)Pd' units, yielding the monomeric derivative [Pd{(3-ClC6H3)CH=NCH2(eta(5)-C5H4)Fe(eta(5)-C5H5)}Cl(PPh3)]. These compounds contain an endocyclic five-membered palladocycle fused with the phenyl ring and arise by activation of a sigma(C-CI) bond. The reactivity of N-(2,6-dichlorobenzylidene)benzylamine and the analogous ferrocenyl Schiff bases is compared.

  Synthesis and characterization of novel Schiff bases derived from aminomethylferrocene of general formula: [(η5-C5H5)Fe(η5-C5H4)CH2=CH(C6H4-2-R)}] with R = Cl (1a) and H (1b) are reported. These react with Na2[PdCl4] and Na(CH3COO)·3H2O in methanol at room temperature producing di-μ-chloro-bridged cyclopallated compounds (2a, 2b) which contain a σ(PdCsp2phenyl) bond. However, for (1b), the activation
