Abstract Treatment of [(η 6-p-cymene)RuCl2]2 with one equivalent of chlorodiphenylphosphine in tetrahydrofuran at reflux afforded a neutral complex [(η 6-p-cymene)RuCl2(κ 1-P-PPh2OH)] (1). Similarly, the reaction of [Ru(bpy)2Cl2·2H2O] (bpy = 2,2′-bipyridine) and chlorodiphenylphosphine in methanol gave a cationic complex [Ru(bpy)2Cl(κ 1-P-PPh2OCH3)](PF6) (2), while treatment of [RuCl2(PPh3)3] with [2-(C5H4N)CH=N(CH2)2N(CH3)2] (L1) in tetrahydrofuran at room temperature afforded a ruthenium(II) complex [Ru(PPh3)Cl2(κ 3-N,N,N-L1)] (3). Interaction of the chloro-bridged complex [Ru(CO)2Cl2] n with one equivalent of [Ph2P(o-C6H4)CH=N(CH2)2N(CH3)2] (L2) led to the isolation of [Ru(CO)Cl2(κ 3-P,N,N-L2)] (4). The molecular structures of the ruthenium(II) complexes 1–4 have been determined by single-crystal X-ray crystallography. The properties of the ruthenium(II) complex 4 as a hydrogenation catalyst for acetophenone were also tested.

摘要 在四氢呋喃中回流处理 [(η 6-p-cymene)RuCl2]2 得到中性配合物 [(η 6-p-cymene)RuCl2(κ 1-P-PPh2OH)] (1) . 类似地，[Ru(bpy)2Cl2·2H2O]（bpy = 2,2'-联吡啶）和氯代二苯基膦在甲醇中的反应得到阳离子络合物 [Ru(bpy)2Cl(κ 1-P-PPh2OCH3)](PF6) (2)，同时在室温下在四氢呋喃中用 [2-(C5H4N)CH=N(CH2)2N(CH3)2] (L1) 处理 [RuCl2(PPh3)3] 得到钌 (II) 配合物 [Ru (PPh3)Cl2(κ 3-N,N,N-L1)] (3)。氯桥连络合物 [Ru(CO)2Cl2] n 与一当量 [Ph2P(o-C6H4)CH=N(CH2)2N(CH3)2] (L2) 的相互作用导致 [Ru(CO) )Cl2(κ 3-P,N,N-L2)] (4)。钌 (II) 配合物 1-4 的分子结构已通过单晶 X 射线晶体学确定。
