  Tricarbonyl Rhenium(I) and Technetium(I) Complexes with Hydrazones Derived from 4,5‐Diazafluoren‐9‐one and 1,10‐Phenanthroline‐5,6‐dione

  摘要：

  AbstractTricarbonylrhenium(I) and ‐technetium(I) halide (halide = Cl and Br) complexes of ligands derived from 4,5‐diazafluoren‐9‐one (df) and 1,10‐phenanthroline‐5,6‐dione (phen) derivatives of benzoic and 2‐hydroxybenzoic acid hydrazides have been prepared. The complexes have been characterized by elemental analysis, MS, IR, 1H NMR and absorption and emission UV/Vis spectroscopic methods. The metal centres (ReI and TcI) are coordinated through the nitrogen imine atoms and establish five‐membered chelate rings, whereas the hydrazone groups stand uncoordinated. The 1H NMR spectra suggest the same behaviour in solution on the basis of only marginal variations in the chemical shifts of the hydrazine protons.

  Durch die Zugabe von Triethylamin erfolgt eine Deprotonierung von Hapbhyd, was zur Bildung von [Re(CO)3(OH2)(apbhyd)] fuhrt. Eine analoge Reaktion mit Hpy2bhyd fuhrt zur Hydrolyse des Proliganden und es entsteht ein Rheniumkomplex mit dem monoanionischen Bis(2-pyridyl)hydroxymethanolato-Liganden, py2C(OH)O}—. Die gleiche Verbindung, [Re(CO)3py2C(OH)O}], entsteht nach Zugabe von Triethylamin und Wasser

  通过 (Et4N)2[Re(CO)3Br3] 与乙酰吡啶苯甲酰腙、Hapbhyd、二（2-吡啶基）酮苯甲酰腙、Hpy2bhyd、双（2-吡啶）酮、py2CO 反应制备了新型铼（I）三羰基配合物，和吡啶醛对苯二醛双腙，pytehyd。当不添加支持碱时，配体保持质子化，并分离出以下复合物：[Re(CO)3Br(Hapbhyd)]、[Re(CO)3Br(Hpy2bhyd-py, hyd)]、[Re(CO)3Br (Hpy2bhyd-py1, py2)]、[Re(CO)3Br(py2CO-N, N)] 和 [Re(CO)3Br(pytehyd)]。三乙胺的加入导致 Hapbhyd 去质子化并形成 [Re(CO)3(OH2)(apbhyd)]，而 Hpy2bhyd 被水解并与单阴离子双（2-吡啶基）羟基甲醇配体 py2C( OH)O}-，形成。同样的化合物，[Re(CO)3py2C(OH)O}]，将三乙胺和水加入到
