O-glycoside synthesis with glycosyl iodides under neutral conditions in 1 M LiClO4 in CH2Cl2

Glycosyl phosphates, imidates, trifluoroacetates, chlorides, and bromides are converted into the respective glycosyl iodides by treatment with LiI or NaI in 1 M solutions of LiClO4 in CH2Cl2. Under these neutral conditions the reactive glycosyl iodides are activated, and react with different glycosyl acceptors to give O-glycosides in moderate yields, with the alpha-anomers predominating. The glycosylation reactions most probably proceed by the initial formation of beta-configured glycosyl iodides from the alpha-configured precursors, and subsequent attack of the glycosyl acceptor on the equatorial iodide from the axial direction.

New halogenation reagent system for one-pot conversion of alcohols into iodides and azides

In situ generation of hydrogen iodide from methane-sulphonic acid/sodium iodide in different solvents was found to be an attractive reagent system for the chemoselective conversion of various alcohols to their corresponding iodides. Moreover, treatment of benzylic and allylic alcohols with this reagent system, followed by substitution with azide ion, produced the corresponding azides in one pot in good yields.

Capture of Iodide by Bismuth Vanadate and Bismuth Oxide: An Insight into the Process and its Aftermath

As a result of the scarcity of iodine, as well as its threat to the environment if it is present in excess, iodine as a waste needs to be captured. Compared with ion-exchange resins and Ag-containing materials, which are popular iodide adsorbents, Bi-containing compounds show some important advantages, such as high iodide-capture capacity and fast kinetics. In this study, two Bi-containing compounds, BiVO4 and Bi2O3, were investigated comprehensively for iodide immobilization. The influence of the pH, iodide/adsorbent ratio, temperature, crystallite size, and competing ions was explored, with a view to optimization of the capture process. Further study of the iodide-adsorbed bismuth compounds confirms that the capture of iodide by BiVO4 and Bi2O3 is a chemisorption process with the formation of bismuth oxyiodide (BixOyIz). Furthermore, iodide ions are able to penetrate into the bulk of BiVO4 and Bi2O3, which is believed to be responsible for their high capture capacity. The application of BixOyIz as a photocatalyst has also been examined in Cr-VI reduction. This result makes the capture of iodide by BiVO4 and Bi2O3 even more environmentally friendly as the photocatalytic application of the iodide-containing adsorbents not only avoids the production of secondary waste but may help to solve other environmental issues.

A novel selective anion receptor for iodide ion: Synthesis, characterization and anion binding

A carbazole-based neutral anion receptor 3 has been designed and synthesized. Anion binding studies carried out using H-1 NMR and UV-visible reveal that this compound showed good selectivity for the iodide ion over other anions. The high selectivity for iodide ion among the anions is attributed mainly to the complementarity of the geometries between the receptor 3 and iodide ion.

Structural diversity in hybrid organic-inorganic lead iodide materials

The structural chemistry of hybrid organic-inorganic lead iodide materials has become of increasing significance for energy applications since the discovery and development of perovskite solar cells based on methylammonium lead iodide. Seven new hybrid lead iodide compounds have been synthesized and structurally characterized using single-crystal X-ray diffraction. The lead iodide units in materials templated with bipyridyl, 1,2-bis(4-pyridyl)ethane, 1,2-di(4-pyridyl)ethylene and imidazole adopt one-dimensional chain structures, while crystallization from solutions containing piperazinium cations generates a salt containing isolated [PbI6](4-) octahedral anions. Templating with 4-chlorobenzyl-ammonium lead iodide adopts the well known two-dimensional layered perovskite structure with vertex shared sheets of composition [PbI4](2-) separated by double layers of organic cations. The relationships between the various structures determined, their compositions, stability and hydrogen bonding between the protonated amine and the iodide ions of the PbI6 octahedra are described.

Methyl iodide, an ozone-safe alternative to methyl bromide as a soil fumigant

Methyl iodide was tested as a possible replacement for methyl bromide as a soil fumigant due to the scheduled removal of methyl bromide from the market. Methyl iodide is a better methylating agent than methyl bromide; it is rapidly destroyed by UV light and therefore unlikely to be involved in stratospheric ozone depletion. In laboratory and field trials, we tested methyl iodide alone or in comparison with methyl bromide for effectiveness in controlling the fungi Phytophthora citricola, P. cinnamomi, P. parasitica, and Rhizoctonia solani; the nematode Heterodera schachtii; and the plants Abutilon theophrasti, Chenopodium album, C. murale, Convolvulus arvensis, Cyperus rotundus, Poa annua, Portulaca oleracea, and Sisymbrium irio. In addition, we compared methyl iodide for biocidal effectiveness with seven other alkyl iodides. In both laboratory and field trials, when compared at equivalent molar rates, methyl iodide was equal to or better than methyl bromide in controlling the tested soilborne plant pathogens and weeds. When compared with other alkyl iodides, methyl iodide was the most effective fumigant.

IODIDE ADSORPTION ON THE SURFACE OF CHEMICALLY PRETREATED CLINOPTILOLITE

The possibility to use the monoionic Ag+- form (eventually Hg+- and Hg2+- forms) of clinoptilolite of domestic origin for radioactive iodide elimination from waters has been studied. The capacity of the monoforms of clinoptilolite towards iodide exceeds many times that of the capacity of clinoptilolite in natural form. Due to the law solubility product of AgI, Hg2I2 and HgI2 iodides generate precipitates on the zeolite surface. Rtg analyses of the silver form of clinoptilolite after sorption of iodide demonstrate the formation of new crystals on the zeolite surface. The influence of interfering anions on the adsorption capacity of silver clinoptilolite towards iodide was investigated, too. Kinetic curves of iodide desorption from the surface of silver and mercury clinoptilolite were compared. Simultaneously, adsorption isotherms for the systems aqueous iodide solution/Ag-, Hg-clinoptilolite were determined.

Surface Passivation of Perovskite Films via Iodide Salt Coatings for Enhanced Stability of Organic Lead Halide Perovskite Solar Cells

Organic-inorganic halide perovskite materials have emerged as attractive alternatives to conventional solar cells, but device stability remains a concern. Recent research has demonstrated that the formation of superoxide species under exposure of the perovskite to light and oxygen leads to the degradation of CH3NH3PbI3 perovskites. In particular, it has been revealed that iodide vacancies in the perovskite are key sites in facilitating superoxide formation from oxygen. This paper shows that passivation of CH3NH3PbI3 films with an iodide salt, namely phenylethylammonium iodide (PhEtNH3I) can significantly enhance film and device stability under light and oxygen stress, without compromising power conversion efficiency. These observations are consistent with the iodide salt treatment reducing iodide vacancies and therefore lowers the yield of superoxide formation and improves stability. The present study elucidates a pathway to the future design and optimization of perovskite solar cells with greater stability.

Acyl iodides in organic synthesis: XI. Unusual N-C bond cleavage in tertiary amines

Acyl iodides reacted with excess primary and secondary amines in a way similar to acyl chlorides, yielding the corresponding carboxylic acid amide and initial amine hydroiodide. Reactions of tertiary amines with acyl iodides were accompanied by cleavage of the N-C bond with formation of the corresponding N,N-di(hydrocarbyl)carboxamide and alkyl iodide. In the presence of excess tertiary amine the latter was converted into quaternary tetra(hydrocarbyl)ammonium iodide.

Infrared reflection spectra of ammonium iodide at high pressure

IR reflection spectra for ammonium iodide at low temperature and at high pressure were used to study different stable phases of ammonium iodide and the transition regions between these stable phases. A modified Kramers-Kronig technique was used to analyze the reflection spectra. The IR reflection spectra of ammonium iodide at high pressure are reported here for the first time, and some of the new insights provided by this data, particularly for the transition regions are discussed.
