通过 (η5 C5H5) 2 Fe2 (CO) 4和硒粉在沸腾的甲苯中反应可制得含 μ3 Se的立方烷簇合物 (η5 C5H5) 4Fe4 (μ3 Se) 4(1) ,而由 (η5 RC5H4 ) 2 Cr2 (CO) 4S在甲苯中回流可制得含 μ3 S的立方烷簇合物 (η5 RC5H4 ) 4Cr4 (μ3 S) 4(2 ,R =COMe ;3,R =CO2 Me)。企图通过 (η5 EtO2 CC5H4 ) 2 Fe2 (CO) 4(5 )和硫黄制备 μ3 S立方烷簇合物 (η5 EtO2 CC5H4 ) 4Fe4 (μ3 S) 4(6 )未获成功 ,其中 5是由 η5 EtO2 CC5H4 Fe(CO) 2 Na与 η5 EtO2 CC5H4 Fe(CO) 2 I (4 )缩合制得。新化合物 1～ 5经元素分析 ,IR和1 HNMR光谱表征
The cubic cluster (η5C5H5) 4Fe4 (μ3Se) 4 (1) containing μ3Se can be obtained by reacting (η5C5H5) 2Fe2 (CO) 4 with selenium in boiling toluene, RC5H4) 2 Cr2 (CO) 4S was refluxed in toluene to obtain cubic Cs3C (η5RC5H4) 4Cr4 (μ3S) 4 (2, R = COMe; 3, R = CO2Me). Attempts to prepare μ3S cubic carbohydrate clusters (η5 EtO2 CC5H4) 4Fe4 (μ3S) 4 (6) via (η5 EtO2 CC5H4) 2 Fe2 (CO) 4 (5) and sulfur have not been successful, CC5H4 Fe (CO) 2 Na and η5 EtO2 CC5H4 Fe (CO) 2 I (4) condensation in the system. New compounds 1-5 were characterized by elemental analysis, IR and 1 HNMR spectroscopy
