中文摘要: |
将双(环戊二烯基)二氯化钛(Cp_2TiCl_2)负载到聚苯乙烯载体上,再与Co_2(CO)_8反应,合成了三种担载的准异核羰基金属簇p(?)CH_2 Cp_2Ti(Cl)OCCo_3(CO)_9。用IR表征结构并研究担载金属簇的热稳定性、乙烯氢甲酰化反应的催化性能及反应机理。 |
英文摘要: |
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. |
