Streszczenie:

Positive ion electron ionization mass spectra are presented for palladium(II) β-diketonates and monothio-β-diketonates of the general form PdII[RC(X)CHC(O)R′]2, where R = phenyl, 4-methoxyphenyl, 2-thienyl, or 2-naphthyl; R′ = trifluoromethyl, pentafluoroethyl, or n-heptafluoropropyl; and X = O or S. The mass spectral behavior is in sharp contrast to that of metals of the first transition series. The spectra of the β-diketonates are dominated by metal-containing ions that arise by migration of the R group from the ligand (L) to palladium, but there is no evidence for fluorine-to-metal transfer

In order to discover new dual-active agents, novel ruthenium (η6-p-cymene) complexes of the general formula [(η6-p-cym)Ru(O–O)Cl] with O,O-diketo ester ligands ethyl 2-hydroxy-4-aryl-4-oxobut-2-enoate (1–3), were synthesized. The complexes 1–3 were characterized by spectral techniques (UV–Vis, IR, 1H and 13C NMR, andESI-HRMS), elemental analysis, and X-ray crystallography. Based on in vitro DNA/HSA experiments, complex 1 exhibited the highest DNA/HSA-activity, suggesting that the presence of an alkene chain contributes to increased activity. The cytotoxic activi

. Triethylaminium trifluoroacetate (CH3CH2)3NH+ ‒O(O)C‒CF3, obtained by reacting tri-fluoroacetic acid with triethylamine, is a colorless ionic liquid that passes into the vapor phase when heated to 200–220 °C. The compound has been characterized by elemental analysis, infrared spectroscopy, 1H and 13C nuclear magnetic resonance, mass spectroscopy, thermogravimetry, differential scanning calorimetry, refractometry, electron absorption and emission spectroscopy. In the UV spectrum there is a weak absorption band in the range of 260–340 nm. When excited at 320 nm, the compound shows two photolum

Electron ionization positive-ion mass spectra are reported for 18 substituted nickel(II) β-diketonates and monothio-β-diketonates, NiII(RCXCHCOR′)2, where X = O or S; R = phenyl, 2-thienyl, 5-methyl-2-thienyl, or 2-naphthyl; and R′ = difluoromethyl, trifluoromethyl, pentafluoroethyl, or n-heptafluoropropyl. Each mass spectrum contains a prominent molecular ion, [NiL2]+, which, for β-diketonates, fragments mainly by elimination of the odd-electron R′• species; the resulting ion decomposes by losses of one or more even-electron neutral species to yield ions containing nickel(II).

In order to demonstrate the role of the fluorination and some solvents in the structural organization of the Ag(I) coordination polymers with β-diketonate ligands (R1C(O)CαHC(O)R2)− we synthesized a series of the compounds containing tfac- (R1 = CH3, R2 = CF3) and pfpac- (R1 = CH3, R2 = C2F5) anions. Solvent-free [Ag(L)]∞ (L = tfac 1, pfpac 2) compounds and the corresponding acetonitrile and toluene adducts have been characterized by elemental analysis and/or NMR, IR and single-crystal XRD. This series includes five new coordination polymers. Compound 1 is a 3D coordination framework based on

Molecular ions, [CoIIIL3]+•, are observed only for some of the more highly fluorinated complexes (R′ = C2F5 or n-C3F7). The [CoIIIL2]+• ion, possibly generated by ionization of CoIIL2 formed by thermal degradation, or by electron ionization of CoIIIL3, typically decomposes by elimination of a radical, i.e., L• or R′•, to yi

Conselho Nacional de Pesquisa e Desenvolvimento Científico e Tecnológico - CNPq<br>In this work a theoretical study was carried out to investigate the spectroscopic properties of trivalent europium complexes. The study was divided into two parts. The first one was the study of the luminescent efficiency of five complexes which had as ligands β-diketones and pyrazole. Pyrazole modifications were made promoting a gradual increase in the amount of fluorine atoms in the search for systems with greater luminescence. The second part was the study of structural elucidation and luminescent efficiency

This study explores the application of an innovative approach for the neutralization of pollutants from sewage sludge, sampled at the Cvetojevac Wastewater Treatment Plant in Kragujevac. The sludge was treated with β-diketonate at different concentrations (50, 100, and 200 mg/mL), and a bioassay method was applied using red clover seeds (Trifolium pratense L.) as a model for germination. The results indicate that the addition of hummus and treatment with synthesized β-diketonate significantly reduced the inhibitory effects of the sludge. The synthesized β-diketonate shows potential for polluta
