A facile large-scale synthesis of the “push–pull”-substituted ligand bis(diethylamino)(pentafluorophenyl)phosphane is reported. A selenophosphorane as well as complexes with CuI and PdCl2, can be formed almost quantitatively from suitable starting materials. The PdII complex shows a square-planar coordination with significant distortions of the Cl–Pd–Cl moiety in the solid state. In contrast, t...

Layers of ethylene carbonate (EC) modified CuI/PVA polymer composites were prepared by growth of CuI nano-particles in an aqueous solution of PVA followed by casting at room temperature. The structural, thermal, optical, electrical and di-electrical characterization of polymer composites was investigated using different techniques. These investigations confirm the growth of CuI nano-particles a...

In the mononuclear title complex, [CuI(CH3CN)(C18H15P)2], the Cu(I) ion is in a distorted tetra-hedral geometry, coordinated by two P atoms of two tri-phenyl-phosphane ligands, one N atom of an aceto-nitrile ligand and one iodide anion. The aceto-nitrile ligand is disordered over two sets of sites in a 0.629 (15): 0.371 (15) ratio. In the crystal, weak C-H⋯I hydrogen bonds link the mol-ecules, ...

The nature of phase equilibria in the Cu3SbS3-CuI binary system over entire concentration range were studied by means powder X-ray diffraction analysis (PXRD) for first time at room temperature. It was found that sample containing 66.7 mol.% CuI composed a single and has pattern completely different from constituent phases under study. crystal lattice type parameters, determined on basis this u...

A combination of experimental and density functional theory (DFT) investigations suggests that the Cu-catalyzed fluorination of unsymmetrical diaryliodonium salts with general structure [Mes(Ar)I]+ in N,N'-dimethylformamide proceeds through a CuI/CuIII catalytic cycle. A low concentration of fluoride relative to combined iodonium reagent plus copper ensures that [Mes(Ar)I]+ is available as the ...

The title compound, [CuI(C(18)H(15)P)(3)]·C(2)H(3)N, was obtained from the reaction of triphenyl-phosphine and copper(I) iodide in acetonitrile. The monomeric form of the complex has slightly distorted coordination of Cu by the I atom and three P atoms. The crystal structure is stabilized by C-H⋯π inter-actions between phenyl H atoms and phenyl rings. In addition, the complex mol-ecules exhibit...

INTRODUCTION This study compared canal and isthmus debridement efficacies between side-vented needle irrigation (SNI) and continuous ultrasonic irrigation (CUI) in the mesial root of mandibular first molars with narrow isthmuses using a closed-canal design. METHODS Micro-computed tomography scanning was used to select 20 teeth, each containing a narrow isthmus. Each root was sealed at the ape...
