Reported in this contribution are the synthesis and characterization of bidentate bis(imino)pyridine Re(I) complexes 2,6-2,6-iPr2C6H3N = CPh}2(NC5H3)Re(CO)3X (X = Br (2), Cl (3), and OSO2CF3 (4)). Compounds 2 and 3 were prepared by direct reaction of bis(imino)pyridine ligand 2,6-2,6-iPr2C6H3N = CPh}2(NC5H3) (1) with Re(CO)5X (X = Br, Cl) in toluene solution at 100 °C. Further treatment of 2 or 3
该贡献的报告是二齿双(亚氨基)吡啶Re(I)配合物2,6- 2,6 - i Pr 2 C 6 H 3 N = CPh} 2(NC 5 H 3)Re(I)的合成和表征CO)3 X(X = Br(2),Cl(3)和OSO 2 CF 3(4))。化合物2和3是由双直接反应制备(亚氨基)吡啶配体2,6- 2,6-我镨2 ç 6 ħ 3 N =器CPh} 2(NC 5H 3)(1)与Re(CO)5 X(X = Br,Cl)在甲苯溶液中的温度为100°C。在两种情况下,用Ag(OSO 2 CF 3)进一步处理2或3均会形成4。新化合物(的分子结构2,3和4通过单晶X射线衍射建立),并通过元素分析和NMR研究证实。
