Treatment of olefins with a mixture of iodine and mercury(II) thiocyanate in benzene or diethyl ether gives vic-iodo(isothiocyanato)alkanes and vic-iodo(thiocyanato)alkanes in a high yield, the former being predominant. Similar results were obtained by using silver(I) and thallium(I) thiocyanates, though both the yield and the selectivity are slightly lower. By use of potassium thiocyanate and copper(I) isothiocyanate in place of mercury(II) thiocyanate, beta -iodo thiocyanates were mainly formed. A reaction scheme involving initial formation of an iodonium ion from olefin and ISCN (formed in situ) and a subsequent attack of complex anion I(SCN)//2** minus has been proposed to account for this predominant formation of beta -iodo isothiocyanates.

We report on the synthesis of TiO2 nanoparticles using nanosecond pulse laser ablation of titanium in liquid, gaseous and supercritical CO2. The produced particles were observed to be mainly anatase-TiO2 with some rutile-TiO2. In addition, the particles were covered by a carbon layer. Raman and x-ray diffraction data suggested that the rutile content increases with CO2 pressure. The nanoparticle size decreased and size distribution became narrower with the increase in CO2 pressure and temperature, however the variation trend was different for CO2 pressure compared to temperature. Pulsed laser ablation in pressurized CO2 is demonstrated as a single step method for making anatase-TiO2/carbon nanoparticles throughout the pressure and temperature ranges 5-40 MPa and 30 C-50 C, respectively.

Application In Synthesis of Cuprous thiocyanate, Healthcare careers for chemists are once again largely based in laboratories, although increasingly there is opportunity to work at the point of care, helping with patient investigation. Mentioned the application of 1111-67-7, Name is Cuprous thiocyanate.

Controllable synthesis of uniformly disk-shaped CuS nanostructures with a narrow size distribution was realized by a lowerature (150 C) solvothermal process using polyvinyl pyrrolidone (PVP) as the surfactant. Monodispersed nanodisks of pure CuS phase with an average diameter of ca. 500 nm could be obtained at a specific S/Cu molar ratio (xS/Cu) of raw materials, which was revealed to affect the phase structure and morphology of the product but the influence of PVP content (xPVP) is limited. The CuS nanodisks have a broad absorption in the visible region and superior photocatalytic performances for the degradation of RhB whose decomposition rate reaches 93% in 2 h, indicating a potential application in the field of wastewater treatment.

A PRIMARY (barrier) film forms on the copper anode at an underpotential relative to the secondary (porous) film and exhibits a pre-peak or shoulder at -0.19 V (vs.SHE), for a 0.1 mol dm-3 KSCN electrolyte.The anodic peak current for the primary film is linearly dependent upon the sweep rate, while potential steps into the primary film region produce monotonic current decays with j = kt-1, consistent with a place-exchange mechanism for the initial formation of the barrier film.Upon stirring, the size of the primary film peak decreases as hydrogen evolution competes with the film-formation process.A porous CuSCN film begins to form at potentials 50-100 mV more positive than the barrier film, producing a larger peak at 0.01 V (0.1 mol dm-3 KSCN), equivalent to a film of 15-20 monolayers, with thicker films formed in more concentrated thiocyanate solutions.The anodic peak current for the porous film and the potential change to reach the peak are both proportional to the square root of the sweep rate, which is consistent with a model for film growth controlled by the resistance across the underlying barrier film.Raman spectroscopy reveals at least two distict S-bonded CuSCN species, one of which is lost upon partial reduction of the film, and is due to the barrier film.The remaining species has the same Raman spectrum as crystalline CuSCN.

Inorganic CsPbBr3 perovskite solar cell (PSC) has attracted much attention owing to its outstanding air and thermal stability and low cost manufacture process. Crystalline TiO2 (c-TiO2) has been widely used as electron-transporting layer (ETL) material for inorganic CsPbBr3 PSC. However, c-TiO2 requires high-temperature (>450 C) fabrication process which impedes the application of flexible inorganic CsPbBr3 PSC and its low electron mobility further limits the performance enhancement. Herein, we prepared novel amorphous Nb2O5 (a-Nb2O5) ETL through a facile room-temperature sputtering method for inorganic planar CsPbBr3 PSC. The PSC with a-Nb2O5 ETL has gained a champion efficiency of 5.74%, which is higher than that of the PSC (5.12% or 4.67%) based on crystalline Nb2O5 (c-Nb2O5) ETL or c-TiO2 ETL by high-temperature (500 C) annealing. The improved photovoltaic characteristic for CsPbBr3 PSC with a-Nb2O5 ETL may be ascribed to its suitable work function, high optical transmittance, low charge recombination at the a-Nb2O5/CsPbBr3 interface and the superior crystallinity of CsPbBr3 film deposited on a-Nb2O5 ETL. Moreover, the a-Nb2O5-based CsPbBr3 PSC without encapsulation exhibits a good long-term stability in ambient atmosphere. This work offers a new research direction for preparing high-performance inorganic PSC.

Seven novel complexes (C1?C7) were synthesized by the interaction between Cu(I) metal cation, L1, L2, L3, X and PPh3, where L1?L3 are derivatives of ((pyridine-2-ylmethylene)amino)phenol imine ligands and X = Cl?, Br?, I?, NCS?. All the complexes were characterized using infrared, 1H NMR and 31P NMR spectroscopies. The crystal structures of C1?C7 were also determined using single-crystal X-ray diffraction. The organization of the crystal structures and the intermolecular interactions are discussed. The supramolecular assemblies are driven by cooperative pi?pi interactions and hydrogen bonds, followed by CH?pi linkages. The potential anticancer effect of C1?C7 was assessed for human glioblastoma cells using several anticancer experiments, which showed that these complexes have marked anticancer property against U87 cells. It was also found that the minimum and maximum anticancer effects are shown by C3- and C4-treated samples, respectively. Furthermore, theoretical approaches were used to investigate the nature of metal?ligand interactions which suggest a closed-shell and electrostatic character for Cu?N, Cu?P and Cu?X bonds.

Reaction of copper(II) thiocyanate with pyrimidine leads to the formation of the new ligand-rich 1:2 (1:2 = ratio metal salt to ligand) copper(II) compound [Cu(NCS)2(pyrimidine)2]n (1). Its crystal structure was determined by X-ray single crystal investigations. It consists of linear polymeric chains, in which the Cu2+ cations are mu-1,3 bridged by the thiocyanato anions. The pyrimidine ligands are terminal N-bonded to the Cu2+ cations, which are overall octahedrally coordinated by two pyrimidine ligands and two N-bonded as well as two S-bonded thiocyanato anions. Magnetic measurements were preformed yielding weak net ferromagnetic interactions between adjacent Cu2+ centers mediated by the long Cu-S distances and/or interchain effects. On heating compound 1 to approx. 160 C, two thirds of the ligands are discharged, leading to a new intermediate compound, which was identified as the ligand-deficient 2:1 copper(I) compound [(CuNCS)2(pyrimidine)]n by X-ray powder diffraction. Consequently, copper(II) was reduced in situ to copper(I) on heating, forming polythiocyanogen as byproduct. Elemental analysis and infrared spectroscopic investigations confirm this reaction pathway. Further investigations on other ligand-rich copper(II) thiocyanato compounds clearly show that this in situ thermal solid state reduction works in general. The Royal Society of Chemistry 2009.
