Palladium(II) induced preferential activation of the σ(Csp3H) versus the σ(Csp2, ferroceneH) bond of (SC)-[(η5-C5H5)Fe{(η5-C5H4)CHNCH(CO2Me)CH2CH2SMe}]
摘要:
The reaction of (S-c)-[(eta(5)-C5H5)Fe{(eta(5)-C5H4)-CH=N-CH(CO2Me)CH2-CH2SMe}] (1) with Na-2[PdCl4] in the presence of NaAcO is studied. This process leads to the formation of the tetrametallic complex: [Pd-2([C{(CO2Me)-CH2-CH2-SMe}N=CH-(eta(5)-C5H4)]Fe(eta(5)-C5H5)}(2)Cl-2].CH2Cl2. The X-ray crystal structure of this complex revealed that the ligand exhibits an unusual mode of binding, and that each palladium is bound to a stereogenic C-sp3* carbon atom.
