2′′-terpyridine-6,6′′-diphosphonate) complexes with NH3 and N2H4 using [RuII(tda-κ-N3O)(dmso)Cl] (dmso is dimethyl sulfoxide) and [RuII(tPa-κ-N3O)(py)2], 8, as synthetic intermediates, respectively. All the new complexes obtained here were characterized spectroscopically by means of UV–vis and NMR. In addition, a crystal X-ray diffraction analysis was performed for complexes trans-[RuII(tda-κ-N3)(py)2(NH3)]
用分子催化剂进行氨(电)氧化是一个快速发展的课题,具有广泛的实际应用前景。我们在此报告了使用 [Ru(tda-κ-N 3 O)(py) 2 ], 2 , (tda 2–是 2,2':6',2''-三联吡啶-6,6''-二羧酸盐;py 是吡啶)作为催化剂前体。此外,我们还描述了与 Ru-tda 和 Ru-tPa(tPa –4是 2,2':6',2''-terpyridine-6,6''-diphosphonate)配合物与 NH反应相关的丰富化学反应3和 N 2 H 4使用 [Ru II (tda-κ-N 3 O)(dmso)Cl](dmso 是二甲亚砜)和 [Ru II(tPa-κ-N 3 O)(py) 2 ], 8分别作为合成中间体。这里获得的所有新配合物都通过紫外-可见光和核磁共振进行光谱表征。此外,还对反式-[Ru II (tda-κ-N 3 )(py) 2 (NH 3 )], 4
