摘要: 配体PyCH2COPh与Ru3(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[(η5-C5H5)Ru(CO)]2(μ-CO)2(2)和[(η5-C9H7)Ru(CO)]2(μ-CO)2(3)。 |

Abstract: The title compound,[PyCH=C (Ph) O]2Ru3(CO)8(1),was obtained from the reaction of PyCH2COPh with Ru3(CO)12 in refluxing toluene.Compound 1 was characterized by IR,1H NMR,and 13C 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[(η5-C5H5) 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). |
