Metal–ion binding by cyclic halogen-bonded structures: A theoretical study using M–(BrZ)4 clusters (Z=F or NH2; M=Li+, Na+, or Mg2+)

30-Aug-2015 | Author(s): Ruben D. Parra, Chemical Physics Letters, 2015

Publication date: 16 September 2015 Source:Chemical Physics Letters, Volume 637 Author(s): Ruben D. Parra The ability of a cyclic halogen-bonded network to bind a metal ion is explored using M–(BrZ)4 complexes (M=Li+, Na+, or Mg2+; Z=F or NH2). Binding is characterized by bond paths ...

Effect of Bromine Substitution on Human Dermal Absorption of Polybrominated Diphenyl Ethers

27-Aug-2015 | Mohamed Abou-Elwafa Abdallah; Gopal Pawar; Stuart Harrad, Environmental Science & Technology, 2015

Human dermal absorption of eight mono- to deca-brominated diphenyl ethers (PBDEs) was investigated for the first time using EPISKIN human skin equivalent tissue. Using a standard in vitro protocol, EPISKIN tissues mounted in specially designed diffusion cells were exposed to the target PBDEs for ...

Matrix effects of carbon and bromine in inductively coupled plasma optical emission spectrometry

26-Aug-2015 | Helmar Wiltsche; Monika Winkler; Paul Tirk, Journal of Analytical Atomic Spectrometry, 2015

In inductively coupled plasma (ICP) based techniques the signal enhancing effect of carbon on some elements like arsenic or selenium is well documented. However, there is a large spread in the reported magnitude of this effect and whether it can be observed for other elements too. In this ...

A Ratiometric Luminescent Thermometer Codoped by Lanthanide and Transition Metals

21-Aug-2015 | Huanrong Li, Zhiqiang Li, Zhaohui Hou, Denghui Ha, Chemistry - An Asian Journal, 2015

Through the combination of lanthanide and transition metal complexes, we herein report a sensitive ratiometric and colorimetric luminescent thermometer valid in a wide temperature range across the cryogenic up to heated zone. Benefiting from the transition metal complex as self‐reference, the ...

Short Access to Belt Compounds with Spatially Close CC Bonds and Their Transannular Reactions

20-Aug-2015 | Pelayo Camps, Tània Gómez, Ane Otermin, Mercè Font‐Bardia, Carolina Estarellas, Francisco Javier Luque, Chemistry - A European Journal, 2015

Abstract Two domino Diels–Alder adducts were obtained from 3,7‐bis(cyclopenta‐2,4‐dien‐1‐ylidene)‐cis‐bicyclo[3.3.0]octane and dimethyl acetylenedicarboxylate or N‐methylmaleimide under microwave irradiation. From the first adduct, a C20H24 diene with C2v symmetry was obtained by Zn/AcOH ...

Mixed‐Valent Selenium Ligands in the Uncharged Iridium Complexes [Ir4Se10Br16] and [Ir6Se8Cl30]

17-Aug-2015 | Karoline Stolze, Bertold Rasche, Michael Ruck, European Journal of Inorganic Chemistry, 2015

Abstract The reaction of Ir with Se and SeBr4 at 200 °C yields shiny vermillion slate‐like crystals of the new compound Ir4Se10Br16. Single‐crystal X‐ray diffraction revealed an orthorhombic unit cell, space group Pccn, with lattice parameters a = 1515.0(1) pm, b = 1534.4(1) pm, and c = ...

Preparation, characterization and properties of four new trivalent lanthanide complexes constructed using 2-bromine-5-methoxybenzoic acid and 1,10-phenanthroline

05-Aug-2015 | Guang-Cai Zong; Jian-Xia Huo; Ning Ren; Jian-Jun Zhang; Xiao-Xia Qi; Jie Gao; Li-Na Geng; Shu-Ping Wang; Shi-Kao Shi, Dalton Transactions, 2015

Four dinuclear trivalent lanthanide complexes of the general formula [Ln2(2-Br-5-MOBA)6(phen)2] (Ln = Nd(1), Sm(2), Ho(3), Er(4); 2-Br-5-MOBA = 2-bromine-5-methoxybenzoate, phen = 1,10-phenanthroline) were prepared and structurally characterized. The complexes 1 to 4 are isostructural with a ...

The addition of bromine and iodine to palladacyclopentadienyl complexes bearing bidentate heteroditopic P−N spectator ligands derived from differently substituted quinolinic frames. The unexpected evolution of the reaction

05-Aug-2015 | Luciano Canovese; Fabiano Visentin; Thomas Scattolin; Claudio Santo; Valerio Bertolasi, Dalton Transactions, 2015

We have synthesized two palladacyclopentadienyl derivatives bearing bidentate ligands heteroditopic 8-(diphenylphosphino)quinoline or 8-(diphenylphosphino)-2-methylquinoline. We have reacted the palladacyclopentadienyl complexes with Br2 and I2 to gain clues on the formation mechanism of the ...
