摘　　要：合成了一种新的钌膦配合物[RuCl2(Dmpp)2en](Dmpp=4-(2,6-二甲氧吡啶基)二苯基膦,en=乙二胺),对其结构进行了表征.系统研究了反应温度,氢气压力,底物和催化剂的比例,碱和催化剂的比例等反应条件对[RuCl2(Dmpp)2en]催化的芳香酮加氢反应活性的影响,证明其在苯乙酮加氢反应中具有很好的催化活性.A new complex, (Dmpp=4(2, 6\|dimethoxy\|pyridyl)diphenylphosphine, en= NH\-2CH\-2CH\-2\|NH\-2), has been synthesized and characterized by \{\}\+1H NMR, \{\}\+\{31\}P{H}NMR.The catalytic activity of \-2e was studied in the hydrogenation of aromatic ketones in the presence of base. Effect of the reaction temperaturure, hydrogen pressure, and the ratio of substrate to catalyst and base to catalyst on the activity are investigated. The has been found to be a good catalyst in the hydrogenation of simple aromatic ketones.
