    An effective non-chromatographic method for the purification of phenanthrolines and related ligands
    摘要:
    1,10-Phenanthrolines are widely employed as ligands, but their use on a large scale is constrained by their difficult purification, which usually requires lengthy chromatographic separations. Herein, we describe a purification strategy that takes advantage of the high stability and low solubility of phenanthroline complexes to separate them from the by products of their synthesis. The formation of ZnCl2 complexes was employed, from which the free ligand can be recovered by reaction with aqueous NH3 in a biphasic CH2Cl2/H2O system. The same strategy was also successfully employed to purify related quinolino-guanidine ligands, demonstrating that the procedure is of general applicability. (C) 2020 Elsevier Ltd.

EPR measurements of C1 and C2 indicate that in solution the dinuclear complexes decompose to mononuclear species. Contrastingly, the EPR spectra of C3 and C4 show that these acetato complexes remain polynuclear in CH 3 CN. The

    The guanidine–quinoline ligand dimethylethyleneguanidinoquinoline (DMEGqu) is able to stabilise bis(chelate) copper complexes in an intermediate geometry between tetrahedral and square-planar environments. The structures of the obtained complexes model the entatic state and have been investigated in solid state by single-crystal X-ray diffraction and in the solid state and in solution by X-ray absorption

    Abstract

    Novel Sn(IV) complexes with the guanidine-quinoline hybrid ligand DMEGqu are reported. With SnCl4, SnBr4, Me2SnCl2, Me2SnBr2, and the 3,5-di-tert-butyl-catecholate coligand complexes with different donor sets were synthesized. Four of these tin compounds have been modelled by density functional theory. Additionally, a tetranuclear Sn(IV) oxocluster with a novel structure motif, a distorted hetero-adamantane with bridging oxido and hydroxido ligands, is presented

  • A Comprehensive Study of Copper Guanidine Quinoline Complexes: Predicting the Activity of Catalysts in ATRP with DFT

    Copper complexes of the hybrid guanidine ligands 1,3‐dimethyl‐N‐(quinolin‐8‐yl)‐imidazolidin2imine (DMEGqu) and 1,1,3,3‐tetramethyl‐2‐(quinolin‐8‐yl)‐guanidine (TMGqu) have been studied comprehensively with regard to their structural and electrochemical properties and their activity in atom transfer radical polymerization (ATRP). A simple analysis of the molecular structures of the complexes gives
    杂化胍配体1,3-二甲基-N的铜配合物(喹啉-8基)咪唑啉-2-亚胺(DMEGqu)和1,1,3,3-四甲基-2-(喹啉-8基)胍(TMGqu)已被全面研究结构和电化学性质及其在原子转移自由基聚合(ATRP)中的活性。对复合物的分子结构进行简单分析并不能说明它们在ATRP中的活性。然而,借助DFT和NBO分析,可以完全阐明特定配位给体对电化学性能的影响。利用适当的DFT方法和新近应用的理论等渗反应,可以预测含有DMEGqu和TMGqu配体的铜络合物的氧化还原电位的相对位置。此外,可以预测DMEGqu或TMGqu的复合物在ATRP中是否更活跃。四个新铜我络合物在标准ATRP反应中进行了测试,无论是在体积和在溶液动力学研究。可以证明具有DMEGqu的复合物具有较低的氧化还原电位,并且在ATRP中更具活性,尽管四甲基胍部分代表更强的供体。
