摘要

<,正,>, The polymer-supported cluster FeCo3 （CO）,12, （μ3-AuPph,2, CH,2,）（4） has been synthesized through reaction of CH,2, ph,2, PAuCl with the cluster anion FeCo,3, （CO）,12,-,. They are characterized through IR spectra, electronic spectra and XPS, with homogenous analog FeCo,3, （CO）,12, （μ3-AuPph,3,）（3） as reference compound. The cluster （3） and the polymer-supported cluster （4） are good catalysts for hydroformylation of olefins. They have better activity and selectivity than the cluster （1） and （2）.The supported cluster （4） is more stable and has catalytic activity at higher temperature than its homogeneous analog （3）. From the metal core level binding energies in XPS and λ ,max, in electronic spectra, it is found that the metal-metal bonds in （4） are reinforced bypolymer supporter. The cluster （3） and （4） can be reused , and possibly do not fragment to one metal species in the course of catalytic reaction.

The cluster （3） and the polymer-supported cluster （4） are good catalysts for hydroformylation of olefins. They have better activity and selectivity than the cluster （1） and （2）.The supported cluster （4） is more stable and has catalytic activity at higher temperature than its homogeneous analog （3）. From the metal core level binding energies in XPS and λ,max, in electronic spectra, it is found that the metal-metal bonds in （4） are reinforced bypolymer supporter. The cluster （3） and （4） can be reused , and possibly do not fragment to one metal species in the course of catalytic reaction.
