POLYMER-SUPPORTED CLUSTER II SYNTHESIS, CHARACTERIZATION AND CATALYTIC PROPERTIES OF POLYMERSUPPORTED HETEROPENTAMETALLIC CLUSTER FeCO3 (CO)12 (μ3-AuPph2CH2■-■)*
摘要:
The polymer-supported cluster FeCo3 (CO)12 (μ3-AuPph2 CH2) (4) has been synthesized through reaction of CH2 ph2 PAuCl with the cluster anion FeCo3 (CO)12-. They are characterized through IR spectra, electronic spectra and XPS, with homogenous analog FeCo3 (CO)12 (μ3-AuPph3) (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 λmax in electronic spectra,it is found that the metal-metal bonds in (4) are reinforced by polymer supporter.The cluster(3) and (4) can be reused,and possibly do not fragment to one metal species in the course of catalytic reaction.
