Synthesis of tertiary arsines containing N,N'-dimethylaminobenzyl group

983-985Tertiary arsines of the type [RAs(C6H4CH2NMe2)2] (R = Me, Et, Ph) and [Me2As(C6H4CH2NMe2)] have been prepared by the salt elimination reactions of Li[C6H4CH2NMe2)] with an appropriate organoarsenic (III) halide. These arsines have been characterized by elemental analysis, IR, mass and NMR (1H and 13C) spectral data

Triphenylantimony(V)dichloride molecular adducts with some thiosemicarbazones

1667-1671The reaction of triphenylantimony(V)dichloride with one mole equivalent of thiosemicarbazone ligands yields the molecular adducts of the type Ph3SbCl2. NᴖS (NᴖS = thiosemicarbazones). These compounds have been characterized by elemental analysis, IR and 1H and 13C NMR spectral data and conductometric measurements. The structures of these molecular adducts have been proposed on the basis of spectroscopic data

One-Pot Synthesis of Pd-Based Ternary Pd@CdS@TiO2 Nanoclusters via a Solvothermal Route and Their Catalytic Reduction Efficiency toward Toxic Hexavalent Chromium

In this work, we report the synthesis of Pd-based ternary Pd@CdS@TiO2 nanocomposites using molecular precursors. This method is facile, less time-consuming, and cost-effective. This catalyst is prepared within 2 h by a solvothermal route using molecular precursors. Information about the phase, morphologies, elemental mapping, and composition of the nanocomposites was obtained using various characterization techniques. The catalytic activity of the as-prepared Pd-based ternary Pd@CdS@TiO2 nanocomposites exhibits effective reduction efficiency for the conversion of toxic Cr­(VI) to Cr­(III) using formic acid as a reducing agent within 5–7 min. To the best of our knowledge, this is the first report on Pd-based ternary Pd@CdS@TiO2 nanocomposites prepared by a solvothermal route and used as catalysts toward the reduction of hexavalent chromium at room temperature

Synthesis and characterization of dibutylgermanium(IV) dialkylthiophosphates

809-810The reaction of dibutylgermanium dichloride with two molar equivalents of ammonium dialkylthiophosphates in benzene. yields dibutylgermanium bis(dialkylthiophosphates), [Bu”2Ge{(OSP(OR)2}2] (R=Et, Pr", Pr', Bu").The latter complexes have been characterized by phosphorus analysis, IR and NMR (1H, 13C and 31P) data. The spectroscopic data suggest that these complexes contain four-coordinate germanium with monodentate dialkylthiophosphate ligand

Designing the morphology of PbS nanoparticles through a single source precursor method

The synthesis and characterization of lead sulphide nanoparticles using complexes as single sources of both lead and sulphur are reported. A cubic phase of galena perfectly matched all synthesized nanoparticles confirming that no secondary product was generated. The complexes prepared from thiosemicarbazide materials and lead bromide reacted differently in oleylamine to produce PbS nanoparticles. Smaller cubic shapes and quantum dots with a blue-shifted absorption were yielded from cinnamaldehyde thiosemicarbazide and benzophenone thiosemicarbazide complexes due to larger ligands and the symmetrical position of the thiosemicarbazide group in benzophenone complex. Relatively larger particles were obtained from acetophenone thiosemicarbazide complex. The temperature of synthesis also affected the shape and size of PbS nanoparticles
