| 中文摘要: |
| This paper deals with a study of hydroformylation of ethylene catalyzed by homoge-neous metal clusters.〔PhCH_2Me_3N〕〔FeCo_3(CO)_(12)〕and〔PhCH_2Me_3N〕〔RuCO_3(CO)_(12)〕show high catalytic activity for the hydroform ylation of ethylene compared with YCCo_3(CO)_9,CO_4(CO)_(10)(PPh)_2,Co_2(CO)_6(PBu_3)_2,and Fe_2(CO)_4(C_5H_5)_2.The reacton rate ofheteronuclear clusters is faster than that with homonuclear clusters.The effect of tempera-ture and pressure on hydroformylation of ethylene with〔PhCH_2Me_3〕〔FeCo_3(CO)_(12)〕ascatalyst was studied.The experimental results.show that the conversion of ethylene exceeds90% with a selectivity up to 95% at temperature 130℃ and pressure 3.9 MPa.When studiedwith high pressure in situ infrared spectroscopic method,PhCCo_3(CO)_9 was found to havehigher thermostability than 〔PhCH_2Me_3N〕〔FeCo_3(CO)_(12)〕. |
