chloro(benzonitrile)ruthenium(II) complex, whereas the bis(benzonitrile)ruthenium(II) complex was obtained with BPG. The cis(Cl,N(amino))-[RuCl(TPA)(Me2SO)]+ complex is thermodynamically much less stable than the trans isomer and isomerizes in dimethyl sulfoxide at 65-100 degrees C. Oxygenation of alkanes catalyzed by these ruthenium(II) complexes has been examined. The chloro(dimethyl sulfoxide-kappaS)ruthenium(II)
具有四齿配体的新钌(II)配合物,例如三(2-吡啶甲基)胺(TPA),三[2-(5-甲氧羰基)吡啶甲基]胺[5-(MeOCO)3-TPA],三(2-已经制备了喹啉基甲基)胺(TQA)或双(2-吡啶基甲基)甘氨酸盐(BPG)。配体与[RuCl2(Me2SO)4]的反应产生了含有TPA或BPG的氯(二甲基亚砜-κS)钌(II)配合物的反式和顺式异构体的混合物,而反式(Cl,N对于5-(MeOCO)3 -TPA和TQA选择性地获得了(氨基))异构体。[RuCl(TPA)(Me2SO)] +配合物的反式和顺式异构体很容易通过分级重结晶分离。反式和顺式(Cl,N(氨基))-[RuCl(TPA)(Me2SO)] +配合物和反式(Cl,N(氨基))-[RuCl 5-(MeOCO)3- TPA}(Me2SO)] +络合物已通过X射线结构分析确定。TPA与[RuCl2(PhCN)4]的反应生成了氯(苄腈)
