Catalytic effects of metal chelate compounds.
This paper is essentially a progress report on the developments in the field of metal chelate catalysis since the first review of this subject fifteen years ago'. For the purpose of defining the scope of this field, metal chelate catalysis is considered to include any reaction that is altered or modified by metal ions through chelate ring formation, as well as reactions of metal chelates themse...
متن کاملIonic liquids with metal chelate anions.
A series of stable (air, water stable and with good thermal stability) and hydrophobic ionic liquids based upon metal chelate anions were synthesized, which were shown to be effective, mild, and easy to recycle catalysts at the same time stable solvents for the oxidation of cyclohexene.
متن کاملThermochromic and solvatochromic Nafion films incorporating cationic metal-chelate complexes.
Nafion films incorporating cationic nickel complexes [Ni(II)(acac)(R4en)](+) (acac = acetylacetonato, R4en = tetraalkylethylenediamine) that exhibit chromic behavior in response to temperature changes and solvent molecules in the vapor and liquid phases have been prepared.
متن کاملDiscussion: Enterochromaffin-Like Cell Pathobiology
The regulation of gastric acid secretion is a complex system, which has been elucidated over a number of years. The significance of the primary role of histamine as a stimulant of the parietal cell was proven conclusively by the demonstration of the efficacy of H2-receptor blockers [1]. The involvement of the vagal and neural system, primarily via muscarinic receptors, appears important, but it...
متن کاملColorimetric filtrations of metal chelate precipitations for the quantitative determination of nickel(II) and lead(II).
A colorimetric filtration method has been developed for the highly selective and sensitive determination of Ni(2+) and Pb(2+) ions. Determinations of Ni(2+) and Pb(2+) follow the filtration using nioxime (1,2-cyclohexanedione dioxime) and rhodizonic acid disodium salt, respectively, as colorimetric reagents. Different from regular instrumentation techniques, the metal chelate precipitations are...
