Thio derivatives of β-diketones and their metal chelates. XX. Magnetic moments of some ruthenium(III) chelates of fluorinated Monothio-β-diketones

Arylazo derivatives of some fluorinated β-diketones and their metal complexes

Phenylazo and benzothiazolylazo derivatives of trifluoroacetylacetone andhexafluoroacetylacetone have been synthesized and characterized. Analytical and spectral datarevealed the existence of phenylazo derivatives in the intramolecularly hydrogen-bonded ketohydrazoneform while the benzothiazolylazo derivatives in the azo-enol form. The monobasicbidentate coordination of the phenylazo derivative...

The Metal Chelates of Heterocyclic /3-Diketones and their Derivatives, Part IV New Mixed Ligand Tetrakis Complexes of Lanthanides Derived from tris-Acetylacetonates and Some 4-Acyl Pyrazolones

The preparation of Lanthanon octa-coordinated mixed chelates with different types of ligands is uncommon. Thompson and Loraas [1] have shown the presence of octacoordinated mixed chelates in solution. Recently, Dutt and Sur [2] have actually isolated several mixed tetrakis compounds of La, Pr, Nd, and Sm with three acetylacetone (Acac) molecules, the other ligands being propionylacetone or benz...

Cytotoxicity of ruthenocene-containing β-diketones.

BACKGROUND Ferrocene-containing β-diketones and cisplatin, [(NH(3))(2)PtCl(2)], possess strong antineoplastic activity. No information is available regarding the anticancer activity of the corresponding ruthenocene complexes. This study examined the cytotoxicity of stable ruthenocene-containing β-diketones. The results were related to the cytotoxicity of cisplatin and the ease of ruthenium elec...
