a series of ruthenium carbonyl complexes PyCH = C(Ph)O][PyCH = C(Ph))Ru(CO)2 (5) and [PyCH2CH(Ph)O]2Ru3(CO)8 (6), [PyCH = C(4-CH3C6H4)O]2Ru3(CO)8 (7), [PyCH2CH(4-ClC6H4)O]2Ru3(CO)8 (8) and [PyCH2C(CH3)2O]Ru3(CO)8 (9) respectively. Five new complexes 5–9 were characterized by elemental analysis, IR, 1H NMR and 13C NMR spectroscopy. The crystal structures of complexes 5–8 were determined by X-ray crystal
摘要吡啶醇PyCH2CH(Ar)OH [Ar = Ph(1),4-CH3C6H4(2),4-ClC6H4(3)]和PyCH2C(CH3)2OH(4)与Ru3(CO)12的反应回流甲苯得到一系列钌羰基配合物PyCH = C(Ph)O] [PyCH = C(Ph))Ru(CO)2(5)和[PyCH2CH(Ph)O] 2Ru3(CO)8(6), [PyCH = C(4-CH3C6H4)O] 2Ru3(CO)8(7),[PyCH2CH(4-ClC6H4)O] 2Ru3(CO)8(8)和[PyCH2C(CH3)2O] Ru3(CO)8 (9)分别。通过元素分析,IR,1H NMR和13C NMR光谱分析了5个新的5-9配合物。配合物5-8的晶体结构通过X射线晶体衍射分析确定。此外,已经研究了配合物6的反应性,当在回流的甲苯中用环戊二烯处理6时,得到双核金属羰基配合物[(η5-C5H5)Ru(CO)]
