  Acid directed in situ oxidation and decarboxylation of 4,4′,6,6′-tetra-methyl-2,2′-bipyridine: Synthesis and structural characterisation of 4,4′,6-tri-carboxy-2,2′-bipyridine and its copper(II) coordination polymer

  摘要：

  The reaction of either 4,4',6,6'-tetramethyl-2,2'-bipyridine, L, or 4,4',6,6'-tetracarboxy-2,2'-bipyridine, H4L, with Cu(OAc)(2)center dot H2O under acidic hydrothermal conditions (50:1 H2O/HNO3; 160 degrees C) led to the formation of crystalline {[Cu(HL')(H2O)]center dot H2O}, 1, which was structurally characterised to identify H3L' as 4,4',6-tricarboxy-2,2'-bipyridine. Clearly, in situ mono-decarboxylation of a tetracarboxylic acid ligand gave the tricarboxy-analogue, H3L'. The structure of 1 consists of a 1D coordination polymer that cross-links through hydrogen-bonding between adjacent carboxylic acid and carboxylate groups, as well as through an aqua ligand and lattice water molecule, to form a densely interconnected 3D network. Regioselective mono-decarboxylation of L or H4L at the 6'-carboxylic acid position may also be affected by heating L or H4L in acidic solution under hydrothermal conditions (2:1 H2O/HNO3; 160 degrees C) to yield crystalline 4,4',6'-tricarboxy-2,2'-bipyridinium nitrate hydrate {[H4L'][NO3]center dot H2O}, 2, which was also structural characterised. The structure of 2 features an array of hydrogen-bonding interactions that generate a 3D network. More forceful heating of the acidic solution at 180 degrees C led to double decarboxylation and the formation of 4,4'-dicarboxy-2,2'-bipyridine, whereas heating at 200 degrees C led to total decarboxylation and the formation of 2,2'-bipyridine. Details of the structures of 1 and 2 along with their synthesis are discussed. (C) 2012 Elsevier B. V. All rights reserved.

  用于从废水中去除高铼酸盐的超稳定锆基阳离子金属-有机框架

  摘要：

  从核废水中有效去除放射性99 TcO 4 -阴离子仍然是一个非常困难的未解决的问题。需要具有高稳定性、阴离子交换能力、优良选择性和可回收性的功能性吸附材料来解决这一问题。在这项工作中，我们设计了两种稳定的阳离子金属-有机骨架 (MOF)——Zr-tcbp-Me 和 Zr-tcpp-Me——可能用作吸附材料以去除99 TcO 4 –. 两种化合物均通过四羧酸配体与锆盐的溶剂热反应合成，然后进行合成后修饰（N-甲基化）。两种锆基 MOF 的结晶度在恶劣条件下都能很好地保持，并且它们对 ReO 4 -阴离子（一种99 TcO 4 -的非放射性类似物）表现出高吸附能力和选择性。Zr-tcbp-Me 和 Zr-tcpp-Me 在所有先前报道的阳离子 MOF 中表现出对酸度的最高框架稳定性，这些阳离子 MOF 已经过从废水中去除高铼酸盐的测试。

• A simple and environmentally benign synthesis of polypyridine-polycarboxylic acids

  An oxidation method using dilute nitric acid solutions under solvothermal conditions has been developed to synthesise a series of polypyridine-polycarboxylic acids. It has been successfully applied to a range of methyl substituted polypyridines including symmetrical and asymmetrical 2,2'-bipyridines; 2,2':6',2 ''-terpyridines and; 2,2':6',2 '':6 '',2'''-tetra-pyridines and yields crystalline polypyridine-polycarboxylic acids in a single step. Simple product recovery through filtration yields a recyclable filtrate. More forcing conditions led to demethylation of the polypyridine ligand most probably via decarboxylation. This simple approach avoids potentially harmful metal-based oxidants and negates any issues associated with the disposal of their resultant (hazardous) waste. (C) 2010 Elsevier Ltd.
