The present study was carried out by focusing on the interaction between molecular complexes crown and thiacrown ethers such as 15-crown-5 (15C5), thia-15-crown-5 (T15C5), dithia-15-crown-5 (DT15C5) with homogeneous and heterogeneous dihalogens (XY) such as I2, IBr, ICl, Br2, Cl2 in the gas phase and in dichloromethane solvent through applying density function theory (DFT) as well as Gaussian 9...

Single crystals formed from hydrogen-bonding supramolecular cations of o-aminoanilinium (HOPD)­crown ethers, (HOPD)([12]crown-4), (HOPD)([15]crown-5), and (HOPD)([18]crown-6), and one-electron-reduced [PMo12O40] Keggin-type clusters were synthesized. The crystal structures and dielectric responses of the three new compounds (HOPD)4([12]crown-4)4[PMo12O40]¢4CH3CN (1), (HOPD)4([15]crown-5)4[PMo12...

Asse II salt mine, in Germany, contains low and intermediate-level radioactive waste that must be retrieved the upcoming years. Potentially contaminated salts brines will require treatment, with 137Cs being main contaminant. Cs+ is problematic to selectively recover due its chemical similarity Na+ K+ which are present high quantities a mine. This paper offers novel solution for separation from ...

Intramolecular cyclic etherification of 1,3-diols was investigated using iodine as a catalyst under solution reaction conditions. Compounds containing five-membered ether rings were obtained. Propella ether (11-oxatricyclo[4.4.3.0(1,6)]tridecane) was conveniently synthesized from 1,3-diol (6-(2-hydroxyethyl)spiro[4.5]decan-6-ol) in 97% yield via carbon skeleton rearrangement. Spiroethers and bi...
