摘要： 通过η5>-R1C5H4(CO)3MNa与η5-R2C5H4(CO)3MNa(M=Mo,W)以及η5-R1C5H4(CO)3MoNa与η5-R2C5H4(CO)3WNa在Fe2(SO4)3醋酸水溶液作用下的交叉氧化偶联反应,合成了7个新的非对称型金属单键化合物η5-R1C5H4(CO)-3Mo─Mo(CO)3C5H4R2-η5(R1,R2:C(O)Me,CO2Et),η5>-R1C5N4(CO)3W─W(CO)3C5H4R2-η5>(R1,R2:C(O)Me,CO2Et;H,CO2Et)和η5>-R1C5H4(CO)3Mo─W(CO)3C5H4R2-η5>(R1,R2:C(O)Me,H;Et,C(O)Me;C(O)Me,n-Bu;CO2Me,n-Bu).用C/N分析、IR、1HNMR和MS表征了它们的结构,并对该氧化偶联反应的特点进行了讨论。

Abstract: Seven new metal-metal singly bonded compounds of the unsymmetrical type η5>-R1>C5H4(CO)3Mo-Mo(CO)3C5H4R2>-η5>(R1>, R2>:C(O)Me, CO2Et), η5>-R1>C5H4(CO)3W-W(CO)3C5H4R2>-η5>-(R1>, R2>:C(O)Me, CO2Et;H, CO2Et) andη5>-R1> C5H4(CO)3Mo-W(CO)3C5H4R2>-η5>(R1>, R2>:C(O)Me, H; Et, C(O)Me; C(O)Me, n-Bu; CO2Me, n-Bu)have been successfully synthesized by oxidative coupling reaction between η5>-R1>C5H4(CO2)2MNa and η5>-R2>C5H4(CO)3MNa(M=Mo, W) and between η5>-R1> C5H4(CO)3MoNa and η5>-R2>C5H4(CO)3WNa in the presence of Fe2(SO4)3/HOAc/H2O reagents. The structures of 1-7 were well characterized by C/Hanalysis, MS, IRand 1H NMRspectroscopy, and the features of this kind of reaction were discussed briefly.
