PhNC(R)NHPh (R=H, Me, Et, Ph), and 1,3-diaryltriazenes, ArNNNHAr (Ar=p-C6H4X, X=H, Cl, Me, OMe) react with ruthenium(II) complexes, [RuCl2(C7H8)]n, [RuCl2(CO)2]n and [RuCl2(Me2SO)4] in the presence of a base (NEt3 or Na2CO3) to afford a selection of bis(chelate) products [RuPhNC(R)NPh}2L2] and [Ru(ArNNNAr)2L2] (L=CO, Me2SO; L2=C7H8). In contrast one particular combination — [RuCl2(Me2SO)4]/PhNC(H)NHPh/NEt3
摘要N,N'-二苯基am,PhNC(R)NHPh(R = H,Me,Et,Ph)和1,3-二芳基三氮烯,ArNNNHAr(Ar = p-C6H4X,X = H,Cl,Me,OMe)在碱(NEt3或Na2CO3)存在下,与钌(II)配合物,[RuCl2(C7H8)] n,[RuCl2(CO)2] n和[RuCl2(Me2SO)4]反应,得到双(螯合物)产物[Ru PhNC(NP)NPh} 2L2]和[Ru(ArNNNAr)2L2](L = CO,Me2SO; L2 = C7H8)。相反,在回流的二甲基甲酰胺中,一种特定的组合[RuCl2(Me2SO)4] / PhNC(H)NHPh / NEt3产生新的am片段化产物[RuCl(NH2Ph)PhNC(H)NPh}(Me2SO)2],其具有用X射线衍射法表征。
