三核钌簇合物[PyCH=C(Ph)O]_2Ru_3(CO)_8的合成、结构及反应性（英文）
|
摘要
配体PyCH_2COPh与Ru_3(CO)_(12)在甲苯中加热回流,得到了标题簇合物[PyCH=C(Ph)O]2Ru3(CO)8(1)。通过红外光谱、核磁共振氢谱和碳谱对1的结构进行了表征,用X射线单晶衍射法测定了1的结构。结果表明:3个钌原子呈等腰三角形分布,其中Ru(2)-Ru(1)和Ru(2)-Ru(1)i的键长均为0.280 nm,Ru(1)-Ru(1)i的键长为0.307 nm。同时研究了簇合物1与环戊二烯及茚的反应,分别得到双核钌羰基配合物[(η~5-C_5H_5)Ru(CO)]_2(μ-CO)_2(2)和[(η~5-C_9H_7)Ru(CO)]2(μ-CO)_2(3)。
The title compound, [PyCH=C(Ph)O]_2Ru_3(CO)8(1), was obtained from the reaction of PyCH_2COPh with Ru_3(CO)12in refluxing toluene. Compound 1 was characterized by IR,1H NMR, and13 C NMR spectroscopy as well as by single-crystal X-ray diffraction analysis. X-ray study of the cluster compound 1 shows that the three ruthenium atoms define an isosceles triangle with two distances of 0.280 nm and one of 0.307 nm. When 1 was treated with cyclopentadiene in refluxing toluene, dinuclear metal carbonyl complexes [(η~5-C_5H_5)Ru(CO)]_2( μ-CO)2(2) was obtained. Similar treatment of 1 with indene gave the product [(η5-C9H7)Ru(CO)]_2(μ-CO)_2(3).
