TL;DR: The combination of two bidentate ligands, the thenolytrifluoroacetone and the Lewis base phenanthroline or dipyridyl, produces a very strong synergic effect in solvent extraction of lanthanides and bivalent transition metals as mentioned in this paper.

TL;DR: By direct titration calorimetry, the equilibrium constants and the enthalpy, entropy and free energy changes of the reaction MA 2 + L → MA 2 L, leading to the formation of synergic adducts of 1,10-phenanthroline, 2,2′-dipyridyl and 4,4′-Dipyride with several bis-(β-diketonato) copper and zinc chelates have been determined in chloroform solution at 25°C as mentioned in this paper.

TL;DR: In this paper, it was shown that the field of metal ion separations, solvent extraction, and ion exchange in particular, would not be as important as it is today were it not for the discovery and exploitation of the actinides.
Abstract: Both the science and technology of the actinides as we know them today owe much to separation science. Conversely, the field of metal ion separations, solvent extraction, and ion exchange in particular, would not be as important as it is today were it not for the discovery and exploitation of the actinides. Indeed, the synthesis of the actinides and the elucidation of their chemical and physical features required continuous development and improvement of chemical separation techniques. Furthermore, the diverse applications of solvent extraction and ion exchange for metal ion separations as we know them today received significant impetus from Cold War tensions (and the production of metric tons of plutonium) and the development of nuclear power for peaceful uses.

TL;DR: In this article, the influence of the introduction of fluorine-containing substituents on the properties of β-diketones is discussed and a bibliography includes 292 references.
Abstract: The methods of synthesis, the keto–enol tautomerism, the chemical reactions (including the formation of heterocycles), and the applications of fluorine-containing β-diketones are examined. The influence of the introduction of fluorine-containing substituents on the properties of β-diketones is discussed. The bibliography includes 292 references.

TL;DR: For the 1,10-phenanthrolinium and 2,2′-bipyridinium ions and derivatives of these, and stability constants for metal complexes formed by the conjugate bases of these have been compiled from the literature, with critical comments on a number of these.
Abstract: Acidity constants for the 1,10-phenanthrolinium and 2,2′-bipyridinium ions and derivatives of these, and stability constants for metal complexes formed by the conjugate bases of these have been compiled from the literature, with critical comments on a number of these. The data include values determined in non-aqueous or mixed solvents as well as those for a large number of “mixed” metal complexes incorporating these bases and a second ligand. The survey also contains known values for the enthalpies and entropies of formation for the proton- and metal-ion complexes. Insofar as possible the compilation indicates the conditions under which the equilibrium constants apply and the methods by which they were determined.
