Synthesis and characterization of copper and nickel complexes with N-arylpyrrole-2-aldimines
摘要:
A series of 17N-arylpyrrole-2-aldimine ligands has been synthesized by condensation of pyrrole-2-carboxaldehyde and substituted anilines. All CuL2 complexes are square, whereas NiL2 compounds are square, tetrahedral or eventually present a square half arrow right over half arrow left tetrahedral equilibrium. Attempts of chemical oxidation have shown the existence of nickel(III) and copper(III) in solution.

Synthesis, characterization and cancer cell growth inhibition activity of ruthenium(II) complexes bearing bidentate pyrrole-imine ligands
synthesized. These ligands and ruthenium compounds were all characterized by 1H and 13C NMR spectroscopy and some of their structures are also determined by single crystal X-ray crystallography. The Ru-1∼Ru-9 showed excellent GI50 for PC-3 and DU-145 with the range of 3.83–12.13 and 4.25–11.22 μM, respectively. Among of these ruthenium compounds, Ru-6 has the best activity indicating phenyl ring is the key
一系列双齿吡咯亚胺配体[C 4 H 3 NH-(2-CH = NR)](1,R =环己烯基; 2,R = CH 2 CH 2 -1-环己烯基; 3,R = t Bu ;4,R = CH 2 -2-呋喃基;5,R = 2-甲氧基苯基;6,R =苯基;7,R = 3-硝基苯基;8,R = 2,6-二异丙基苯基;9,R = 1。 2,4,6-三甲基苯基),合成和它们相应的钌金属化合物茹(ɳ 6 -p -cymene)[C 4 H ^ 3N-(2-CH = NR)]氯}(Ru的1〜孺-9 )还合成。这些配体和钌化合物均通过1 H和13 C NMR光谱表征,并且其某些结构也通过单晶X射线晶体学确定。的Ru的1〜茹-9显示出优异的胃肠道50的PC-3和DU-145与3.83-12.13和4.25-11.22μM的范围内,分别。在这些钌化合物中,Ru-6具有最佳活性,表明苯环是这些钌化合物亚胺取代基上的关键基团。
