Phosphoryl containing ligand tri-n-octylphosphine oxide (TOPO) in dichloromethane has been used as an extracting agent for tetravalent thorium and trivalent europium ions from their 1 M sodium nitrates. The equilibrium data reveal that both ions are extracted as the complexes at 1:3 metal/ligand ratio. The values of conditional extraction equilibrium constant (Kex) show the superior extract...

The reactions of 1 - chloro - 2 - nitro benzene with 2 - Amino thio phenol yield the 2 - ( ( nitro phenyl ) thio ) aniline and then 2 , 2' - thio dianiline of this compound was prepared . Also the symmetrical potentially pentadentate N 2 O 2 S Schiff base ligand 2 , 2' - ( ( ( thio bis (1 , 2 - phenylene ) ) bis ( azanilidene ) ) bis ( methenilidene ) ) diphenol ( H 2 L ) obtain by added salicy...

A PVC membrane Ni(II) ion selective electrode has been constructed using (1E,2E)-bis(2-aminophenyl)N'1,N'2-dihydroxyethanebis as membrane carrier. The electrode exhibited a goodpotentiometric response for Ni(II) over a wide concentration range 1.0×10-4 to 1.0×10-1M with aslope of 29.4±0.5 mV/decade a and a working pH range of 6.5-9.0. It had a fast response time of≤20s. The best performance was...

Oxovanadium(IV), manganese(II) and copper(II) complexes of a Schiff base ligand derived from 2,4-dihydroxyacetophenone and 1,2-diaminocyclohexane have been encapsulated in the nanocavity of zeolite-Y by flexible ligand method and characterized by metal analysis, IR spectroscopic studies and X-ray diffraction patterns. The encapsulated complexes abbreviated here as CuL-Y, MnL-Y and VOL-Y catalyz...

We have demonstrated a simple and efficient route for the synthesis of a novel imine based tridentate ligand and its Pd-complex to investigate the C-C cross-coupling reactions, that involve column chromatography purification in only one step. The catalytic activity of the newly synthesized catalyst was studied for the Suzuki, Sonogashira and, Heck cross-coupling reactions under mild conditions....

We report the first example of a charge-neutral linear two-coordinate copper(I) complex bearing sterically demanding acenaphthoimidazolylidene-based N-heterocyclic carbene (NHC) ligand. The identity and geometry are confirmed by single-crystal X-ray diffraction (XRD) analysis. is poorly emissive at room temperature, showing either ligand-centered (LC) emission around 340 nm when excited 300 or ...

Functionalizations of highly oxidation and hydrolysis stable mono-cationic rhenium bis-arene complexes [Re(η6-C6H6)2]+ are great interest. We directly built up structural features the well-known Hoechst Dye on coordinated arenes as a model for prospective DNA minor groove binding studies. Extensions aromatic unit with functionalized derivatized benzimidazole moieties resulted in deep orange col...
