On July 15, 2013, Duan, Lele; Wang, Lei; Inge, A. Ken; Fischer, Andreas; Zou, Xiaodong; Sun, Licheng published an article.Category: pyridine-derivatives The title of the article was Insights into Ru-Based Molecular Water Oxidation Catalysts: Electronic and Noncovalent-Interaction Effects on Their Catalytic Activities. And the article contained the following:
A series of Ru-bda water oxidation catalysts [Ru(bda)L2] (H2bda = 2,2′-bipyridine-6,6′-dicarboxylic acid; L = [HNEt3][3-SO3-pyridine], 1; 4-(EtOOC)-pyridine, 2; 4-bromopyridine, 3; pyridine, 4; 4-methoxypyridine, 5; 4-(Me2N)-pyridine, 6; 4-[Ph(CH2)3]-pyridine, 7) were synthesized with electron-donating/-withdrawing groups and hydrophilic/hydrophobic groups in the axial ligands. These complexes were characterized by 1H NMR spectroscopy, high-resolution mass spectrometry, elemental anal., and electrochem. In addition, complexes 1 and 6 were further identified by single crystal X-ray crystallog., revealing a highly distorted octahedral configuration of the Ru coordination sphere. All of these complexes are highly active toward CeIV-driven (CeIV = Ce(NH4)2(NO3)6) water oxidation with oxygen evolution rates up to 119 mols of O2 per mol of catalyst per s. Their structure-activity relationship was investigated. Electron-withdrawing and noncovalent interactions (attraction) exhibit pos. effect on the catalytic activity of Ru-bda catalysts. The experimental process involved the reaction of Pyridine-3-sulfonic acid(cas: 636-73-7).Category: pyridine-derivatives
