of the ligand which is reported, we describe the preparation of complexes with Fe(II)Cl2, Co(II)Cl2, Ni(II)Cl2, Cu(I)Cl, and Zn(II)Cl2 salts. All complexes have been characterized by X-ray diffraction studies as well as by standard spectroscopic techniques. The striking point in this work is the diversity of the structures that are obtained. Co(II) and Zn(II) provide isostructural dinuclear complexes
新的BPMPB配体,即双[1-双(2-吡啶基甲基),1(吡啶基)]丁炔,可以很容易地在已知的甲基吡啶氯和乙炔酸钠的反应中作为副产物获得。已知的末端炔烃取代的三脚架)。该对称配体包含两个相同的配位点,每侧分别具有两个亚甲基吡啶和一个吡啶基,并通过提供半刚性链段的炔烃官能团连接。连同已报道的配体的分子结构,我们描述了与Fe(II)Cl 2,Co(II)Cl 2,Ni(II)Cl 2,Cu(I)Cl和Zn(II)的配合物的制备氯2盐。所有配合物均已通过X射线衍射研究以及标准光谱技术进行了表征。这项工作的显着点是获得的结构的多样性。Co(II)和Zn(II)提供同构双核络合物,其中两个配位位点都占据四面体对称性。Cu(I)络合物也是双核化合物,但在那种情况下,铜原子与炔基部分,两个吡啶和桥连氯化物配位。在13铜配合物的13 C NMR光谱证实,金属中心与溶液中的炔烃配位。Ni(II)的配位导致形成

A base-promoted transition metal-free approach to substituted alkenes using alcohols under aerobic conditions using air as the inexpensive and clean oxidant is described. Aldehydes are relatively difficult to handle compared to corresponding alcohols due to their volatility and penchant to polymerize and autoxidize. Wittig ylides are easily oxidized to aldehydes and consequently form homo-olefination
