We survey the latest advances in quadrupolar halogen (Cl, Br, and I) solidstate nuclear magnetic resonance (SSNMR). The reporting period is from August 2008 through to July 2014; prior work has been covered in a previous review from our group (Widdifield et al. [2]). The past 6 years have witnessed a continued growth in the areas of application of chlorine, bromine, and iodine SSNMR. Such areas...

An inductively coupled plasma mass spectrometer (ICP-MS) was used as an ion chromatographic detector for the speciation of iodine and bromine. Gradient elution using NH4NO3 at pH 10 allowed the chromatographic separation of ionic iodine (I- and IO3-) and bromine (Br- and BrO3-) species in less than 8 min. Effluents from the ion-exchange column were delivered to the nebulization system of ICP-MS...

The degradation process of brominated flame retardant (BFR) and BFR-containing waste computer housing plastic in various supercritical fluids (water, methanol, isopropanol and acetone) was investigated. The results showed that the debromination and degradation efficiencies, final products were greatly affected by the solvent type. Among the four tested solvents, isopropanol was the most suitabl...

The room temperature reaction of a 1 : 1 mixture of phosphorus tribromide (PBr3) and the N-heterocyclic carbene 1,3-bis(2,6-diisopropylphenyl)-imidazol-2-ylidene (IPr) quantitatively affords the Lewis acid-base adduct (IPr)PBr3 (1). Interestingly, when 1 is heated between 55 and 65 °C for a period of several days, dark red crystals slowly begin to form in the reaction vessel accompanied by the ...

Incubation of iodosylbenzene and [125I]iodobenzene with cytochrome P-450 (P-450) leads to the formation of [125I]iodosylbenzene (Burka, L.T., Thorsen, A., and Guengerich, F.P. (1980) J. Am. Chem. Soc. 102, 7615-7616), but to date it has not been possible to observe directly the oxidation of organic halides in NADPH-supported P-450 reactions because of the intrinsic instability of haloso compoun...

background: possibility to trace-label albumin with isotopes results in information concerning its synthesis, breakdown, and distribution in the intra and extra cellular spaces. the iodination of albumin is a widespread procedure used in scientific studies. bromine not only is more reactive and less expensive than iodine, but bonds more easily with many elements. therefore, it could be a suitab...

Oxidized mercury species may be formed in combustion systems through gas-phase reactions between elemental mercury and halogens, such as chorine or bromine. Injection of bromine compounds or brominated sorbents have been shown to affect mercury speciation and removal in coal-fired power plants. This study examines how bromine species affect mercury oxidation in the gas-phase. Experiments were c...
