摘要Reactions of binuclear [Cp*Ir(-Cl)Cl](2) (Cp* = pentamethylcyclopentadienyl), [Cp*Rh(-Cl)Cl](2) and [(p-cymene)Ru(-Cl)Cl](2) with 2 equiv. AgOTf (OTf=O3SCF3) followed by addition of one equiv. (m-pyridyl)N=C(C10H6)C=N(m-pyridyl) (mPy-bian) linker and NiCl2DME (DME=1,2-dimethoxyethane) in methanol gave heterometallic cationic metallacycles [Cp*Ir-4(4)(-Cl)(4)(-mPy-bian)(2)NiCl2](OTf)(4) (1a), [Cp*Rh-4(4)(-Cl)(4)(-mPy-bian)(2)NiCl2](OTf)(4) (1b), and [(p-cymene)(4)Ru-4(-Cl)(4)(-mPybian)(2)NiCl2](OTf)(4) (1c), respectively. All the complexes are characterized by IR, NMR spectroscopy, and elemental analysis. Ni K-edge X-ray absorption spectroscopy (XAS) studies on 1a-1c reveal that nickel is six-coordinate with four nitrogens and two chlorides. Upon activation with MAO, 1a-1c showed moderate to good catalytic activity for ethylene and norbornene polymerization.
