【Abstract】 According of the idea that supported-mononuclear metal complexes could be the precursors of supported metal carbonyl clusters, three Ti-Co heteronuclear clusters were synthesized by the reaction between polymer-attached titanocene and Co2(CO)8(see p. 373).These clusters were characterized by IR spectroscopy, elemental analysis and chemical method.The in situ IR spectra of these supported Ti- Co clusters were investigated under vacuum, nitrogen,Tydrogen, syn-gas atmosphere, and under ethene hydroformylation conditions. The experimentalesults show that supported Ti-Co clusters catalyze the hydroformylation of ethene and its IR spectrarecovered after reaction, but when ethene pressure is 0. 8 MPa the IR spectra of Ti-Co cluster canbe recovered.更多还原
