Abstract Schiff bases obtained by the reactions of substituted aromatic aldehydes with phenyl hydrazine or 2,4-dinitrophenyl hydrazine were synthesized and characterized by spectroscopic methods. Cyclometalated Ru(III) complexes of general formula, namely [Ru(L)(PPh3)2Cl], were synthesized from the Schiff bases via C–H bond activation and characterized by spectroscopic and electrochemical studies.
摘要 合成了取代芳香醛与苯肼或2,4-二硝基苯肼反应得到的席夫碱,并用光谱法对其进行了表征。通式为 [Ru(L)(PPh3)2Cl] 的环金属化 Ru(III) 配合物是由 Schiff 碱通过 C-H 键活化合成的,并通过光谱和电化学研究进行表征。此外,通过 X 射线晶体学确定了其中一种配合物的一种分子结构。通过电化学研究检查了配合物的氧化还原行为,并研究了一种正金属化机制。图形摘要
