A series of six-coordinate ruthenium(II) complexes [Ru(CO)(L x )(B)] (B = PPh3, AsPh3 or Py; L x = unsymmetrical tetradentate Schiff base, x = 5–8; L5= salen-2-hyna, L6= Cl-salen-2-hyna, L7= valen-2-hyna, L8= o-hyac-2-hyna) have been prepared by reacting [RuHCl(CO)(EPh3)2(B)] (E = P or As) with unsymmetrical Schiff bases in benzene under reflux. The new complexes have been characterized by analytical
一系列六配位钌 (II) 配合物 [Ru(CO)(L x )(B)] (B = PPh3, AsPh3 或 Py; L x = 不对称四齿席夫碱, x = 5–8; L5 = salen -2-hyna, L6= Cl-salen-2-hyna, L7= valen-2-hyna, L8= o-hyac-2-hyna) 已通过反应制备 [RuHCl(CO)(EPh3)2(B) ] (E = P 或 As) 与不对称席夫碱在苯中回流。新配合物已通过分析和光谱(红外、电子、1H、31P 和 13C 核磁共振)数据进行表征。所有配合物都被指定为八面体结构。新的配合物是酮转移氢化的有效催化剂,并且对碳-碳偶联反应也表现出催化活性。
