An octahedral ruthenium(III) Schiff base complexes of the type [RuX(EPh(3))(L)] (where, X=Cl/Br; E=As/P; L=dianion of the Schiff bases derived from acetoacetanilide with o-phenylenediamine and salicylaldehyde/o-hydroxyacetophenone/o-vanillin/2-hydroxy-1-naphthaldehyde) have been synthesized from the reactions of equimolar reactions of [RuX(3)(EPh(3))(3)] and Schiff bases in benzene. The new Ru(III) Schiff base complexes have been characterized by elemental analyses, FT-IR, electronic, (1)H NMR and (13)C NMR spectra, EPR spectral studies, powder X-ray diffraction (XRD) and electrochemical studies. The new complexes were found to be effective catalysts for aryl-aryl coupling and the oxidation of alcohols into their corresponding carbonyl compounds, respectively, using molecular oxygen atmosphere at ambient temperature. Further, the new Ru(III) Schiff base complexes were screened for their antibacterial activity against Pseudomonas aeruginosa, Vibrio cholera, Salomonella typhi and Staphylococcus aureaus.
已通过在苯中使[RuX₃(EPh₃)₃]与席夫碱进行等摩尔反应，合成了[RuX(EPh₃)(L)]类型的八面体钌(III)席夫碱配合物（其中，X = Cl/Br；E = As/P；L是由乙酰乙酰苯胺与邻苯二胺和水杨醛/邻羟基苯乙酮/邻香草醛/2-羟基-1-萘醛衍生的席夫碱的二价阴离子）。新的钌(III)席夫碱配合物已通过元素分析、傅里叶变换红外光谱、电子光谱、¹H核磁共振和¹³C核磁共振光谱、电子顺磁共振光谱研究、粉末X射线衍射(XRD)和电化学研究进行了表征。发现这些新配合物分别是在室温下使用分子氧气氛时用于芳基-芳基偶联以及将醇氧化为相应羰基化合物的有效催化剂。此外，还对新的钌(III)席夫碱配合物针对铜绿假单胞菌、霍乱弧菌、伤寒沙门氏菌和金黄色葡萄球菌的抗菌活性进行了筛选。
