New complexes of Dy (III) and Gd with b-diketones containing unsaturated aryl substituents were synthesized. Metal polymers based on synthesized obtained by the method radical polymerization. The composition structure metal are established. It is shown that during polymerization coordination environment central ion remains unchanged. spectral-luminescent cha­racteristics compounds studied. pres...

New ytterbium (III) compounds with β-diketones (2,7-dimethyl-octene-1-dione-3,5 and 2,6-dimethylheptene-1-dione-3,5) their derivatives phenanthroline have been synthesized. The composition chemical structure of the obtained complexes determined by several Phy­sico-chemical investigations. It has shown, that Yb ion coordinates three ligand molecules coordination sphere is supplemented two mole­c...

The influence of the degree π-conjugation in biaroylmethane ligands upon Eu3+ luminescence efficiency corresponding neutral tris-complexes was investigated depth. data obtained by both steady-state and time-resolved measurements gave an inside into electronic energy transfer mechanisms abovementioned complexes. It shown that extension π-system naphthalene moiety comparison to phenyl one lead a ...

An efficient and environmentally benign one-pot condensation of cyclic diketones, aldehydes naphthols was achieved with 1,4-diazabicyclo[2-2-2]octane supported on Amberlyst-15 as a novel catalyst, producing variety benzoxanthenones in good to excellent yields. The advantages this multicomponent reaction include the use heterogeneous solventless conditions simple methodology that is atom-economi...

Thanks to the use of a sustainable FeIII-based deep eutectic solvent (DES) as promoter/reaction medium, alkynes were hydrated under bench-type reaction conditions (45 °C, air, absence co-catalysts or co-solvents). This Fe-DES could be recycled for up eight consecutives runs in any VOC (E factor = 10). Furthermore, is able promote efficient formal oxidation internal into 1,2-diketones, with syst...
