Ru(II) complexes with the general formula [RuCl2(p-cymene)(L1-3)], K1–3, (L1–3: monodentate benzimidazole ligands), [RuCl2(L5–6)(S)], K4–7, (L5–6: tridentate benzimidazole ligands, S: Solvents [methanol or acetonitrile]), and [RuCl2(L5)(L1–2)], K8–9, were synthesized from [RuCl2(p–cymene)]2 dimer and mono- and tridentate benzimidazole ligands. The compounds were characterized by elemental analysis
具有通式[RuCl 2(对-cymene)(L1-3)],K1-3,(L1-3:单齿苯并咪唑配体),[RuCl 2(L5-6)(S)]的Ru(II)配合物,K4-7,(L5-6:三齿苯并咪唑配体,S:溶剂[甲醇或乙腈])和[RuCl 2(L5)(L1-2)],K8-9由[RuCl 2(p –cymene)] 2二聚体和单齿和三齿苯并咪唑配体。通过元素分析,IR,UV-Vis和NMR对化合物进行表征。测试了合成的Ru(II)配合物(K1–9)作为催化剂的存在,在82°C的条件下,使用2-丙醇作为氢源,在KOH存在下将苯乙酮氢化(TH)转化为仲醇。所有配合物都是苯乙酮TH的活性催化剂,在温和条件下(60分钟后,产率最高可达97%)具有良好的收率。
