以2-（5-（吡啶-2-基）-1H-吡咯-2-基）吡啶（HL 1）为原料，PhICl 2为卤化试剂，分别合成了一氯吡咯HL 2、二氯吡咯HL 3和五氯吡咯L 4。HL 3与[Ru（CO）2Cl 2] n2反应，得到双钌（I）配合物[Ru 2（μ-κ2N，N′：κ 1 N ″-L3）2（CO）4]（1）和单钌（II）配合物[Ru（κ 3 N，N′，N ″-L3）（κ2N，N′-L3）（CO）]（2）。所有新合成的化合物均经1H NMR、IR、UV-Vis、元素分析和X-射线衍射表征。结构分析表明，二氯吡咯L3−在1中作为螯合和桥联配体与两个钌原子配位，在2中作为二齿和三齿配体。
The treatment of 2-(5-(pyridin-2-yl)-1H-pyrrol-2-yl)pyridine (HL1) and PhICl2as halogenation reagent generated monochloro-pyrrole HL2, dichloro-pyrrole HL3 and penta-chloro L4. The reaction of HL3 with [Ru(CO)2Cl2]ngave diruthenium(I) complex [Ru2(μ-κ2N,N′:κ1N″-L3)2(CO)4] (1) and monoruthenium(II) complex [Ru(κ3N,N′,N‴-L3)(κ2N,N′-L3)(CO)] (2). All these newly synthesized compounds were fully characterized by1H NMR, IR, UV–Vis spectra, elemental analyses and X-ray diffraction study. The structural analysis shows that dichloro-pyrrole L3−acts as chelating and bridging ligand to coordinate two ruthenium atoms in1, and acts as bidentated and tridentated ligand in2.
