Spin-orbit transitions (2P1/2←2P3/2) of iodine and bromine atoms in solid rare-gases
Pettersson, Mika,Nieminen, Janne
, p. 1 - 6 (1998)
Infrared absorptions of iodine and bromine atoms in solid rare-gases are presented. The isolated atoms are produced by UV-photolysis of HI or HBr in solid Ar, Kr and Xe. The absorptions are characterised by sharp zero-phonon lines and broad structured phonon side bands. Some of the zero-phonon lines are resolved and split into two components, separated by a few wavenumbers. The production of the atoms follow second-order kinetics indicating that the primary hydrogen atom undergoes a secondary reaction with the hydrogen halide producing a halogen atom and a hydrogen molecule. This is supported by the observation of the infrared absorptions of hydrogen molecules in concentrated matrices after photolysis.

Generation of NBr(a1Δ) by the reaction of N3 radicals with Br atoms: A flow reactor source for quenching rate constant measurements
Hewett, Kevin B.,Setser
, p. 335 - 342 (1998)
The reaction between azide radicals (N3) and Br atoms is shown to produce electronically excited NBr(a1Δ) molecules in a room temperature flow reactor. This chemical system provides adequate concentration of NBr(a1Δ) so that this molecule can be systematically studied. The yield of NBr(b1Σ+) is minor. The quenching reactions of NBr(a) with HCl, HBr, HI, NH3, Br2, CF2Br2, and O2 were examined; the rate constants are (22 ± 5) × 10-14, (280 ± 30) × 10-14, (2300 ± 200) × 10-14, (35 ± 3) × 10-14, (2600 ± 300) × 10-14, (37 ± 6) × 10-14, and (230 ± 30) × 10-14 cm3 molecule-1 s-1, respectively.
Catalytic cycle of a divanadium complex with salen ligands in O2 reduction: Two-electron redox process of the dinuclear center (salen = N,N′-ethylenebis(salicylideneamine))
Yamamoto, Kimihisa,Oyaizu, Kenichi,Tsuchida, Eishun
, p. 12665 - 12672 (1996)
In an attempt to provide confirmation for the postulated mechanism of O2 reduction in vanadium-mediated oxidative polymerization of diphenyl disulfide, a series of divanadium complexes containing salen ligand (salen = N,N′-ethylenebis(salicylideneamine)) were prepared, characterized, and subjected to reactivity studies toward dioxygen. A divanadium(III, IV) complex, [(salen)VOV(salen)][I3] (II), was yielded both by treatments of solutions of [(salen)VOV(salen)][BF4]2 (I) in acetonitrile with excess tetrabutylammonium iodide and by electroreduction of I followed by anion exchange with tetrabutylammonium triiodide. The complex II was characterized by a near-infrared absorption at 7.2 × 103 cm-1 (∈ = 60.1 M-1 cm-1 in acetonitrile) assigned to an intervalence transfer band. A crystallographically determined V(III)-V(IV) distance of 3.569(4) A? is consonant with the classification of II as a weakly coupled Type II mixed-valence vanadium (α = 3.0 × 10-2). Oxidation of the cation [(salen)VOV(salen)]+ with O2 in dichloromethane yielded spontaneously the deep blue, mixed valent, divanadium(IV, V) species [(salen)VOVO(salen)]+ which was structurally characterized both as its triiodide (III) and perchlorate (IV) salts. Crystal data for III: triclinic space group P1 (no. 2), a = 14.973(2) A?, b = 19.481(2) A?, c = 14.168(2) A?, α = 107.00 (1)°, β= 115.56(1)°, γ = 80.35(1)°, V = 3561.3(9) A?3, Z = 4, Dcalc = 1.953 g/cm3, μ (MoKα) = 31.74 cm-1, final R = 0.057 and Rw = 0.065. Crystal data for IV: triclinic space group P1 (no. 2), a = 11.923(3) A?, b = 14.25(1) A?, c = 11.368(7) A?, α = 112.92(5)°, β = 92.76(4)°, γ = 99.13(4)°, V = 1743(1) A?3, Z = 2, Dcalc = 1.537 g/cm3, μ (CuKα) = 57.69 cm-1, final R = 0.042 and Rw = 0.061. The complexes III and IV were deoxygenated in strongly acidic nonaqueous media to produce [(salen)VOV(salen)]3+ as a high-valent complex whose reversible two-electron redox couple (VOV3+/VOV+) at 0.44V vs Ag/AgCl has been confirmed. Its ability to serve as a two-electron oxidant provided a unique model of a multielectron redox cycle in oxidative polymerization.

Swiatkowski, Marcin,Kruszynski, Rafal
, p. 642 - 675 (2017)
The coordination compounds of group 12 halides with 2,2′-bipyridine (bpy) and 1,10-phenanthroline (phen), 2[CdF2(bpy)2]·7H2O (1), [ZnI(bpy)2]+·I3 ? (2), [CdI2(bpy)2] (3), [Cd(SiF6)H2O(phen)2]·[Cd(H2O)2(phen)2]2+·F–·0.5(SiF6)2–·9H2O (4), [Hg(phen)3]2+·(SiF6)2–·5H2O (5), [ZnBr2(phen)2] (6), 6[Zn(phen)3]2+·12Br–·26H2O (7) and [ZnI(phen)2]+·I– (8), have been synthesized and characterized by X-ray crystallography, IR spectroscopy, elemental and thermal analysis. Structural investigations revealed that metal : ligand stoichiometry in the inner coordination sphere is 1 : 2 or 1 : 3. A diversity of intra- and intermolecular interactions exists in structures of 1–8, including the rare halogen?halogen and halogen?π interactions. The thermal and spectroscopic properties were correlated with the molecular structures of 1–8. Structural review of all currently known coordination compounds of group 12 halides with bpy and phen is presented.
Reaction of the closo-decaborate anion B10H 10 2- with dichloroethane in the presence of hydrogen halides
Drozdova,Zhizhin,Malinina,Polyakova,Kuznetsov
, p. 996 - 1001 (2007)
The reactions of the closo-decaborate anion with hydrogen halides and dichloroethane have been studied. Irrespective of the hydrogen halide used (HCl, HBr, HI), chlorination to give mono-, di-, and trihalosubstituted products is the major process. The product ratio depends on the hydrogen halide used and on the synthesis temperature and time. The products have been identified by 11B NMR, IR, and ESI mass spectra. The structure of (Ph 3(NaphCH2)P)2B10H8Cl 2 has been studied by X-ray diffraction. The geometry distortion of the closo-decaborate core found in the chlorinated derivatives is retained on further chemical transformations of the compound.
Complexation and reactions of molecular iodine with dimethyl and diethyl sulfoxides
Markaryan,Grigoryan,Sarkisyan,Asatryan,Adamyan
, p. 1801 - 1803 (2006)
The complexation and reactions of molecular iodine with dimethyl sulfoxide and diethyl sulfoxide in the neat sulfoxides and in their mixtrues with water were studied by conductometry, pH-metry, argentometric titration, UV spectroscopy, and GLC analysis. According to the results obtained, molecular iodine initially forms a charge-transfer complex with the sulfoxide, which subsequently undergoes chemical transformations to hydrogen iodide and the corresponding sulfones. A possible reaction mechanism was suggested.

Photodissociation of a surface-active species at a liquid surface: A study by time-of-flight spectroscopy
Furlan, Alan
, p. 1550 - 1557 (1999)
The photochemistry at a gas-liquid interface was investigated by time-of-flight/quadrupole mass spectroscopy (TOF/QMS). A thin liquid film of 4-iodobenzoic acid (IBA), dissolved in glycerol, was irradiated with nanosecond laser pulses at 275 nm. Atomic and molecular iodine were the only photoproducts leaving the liquid after a low-fluence laser pulse (2). The amount of released I atoms was 2 orders of magnitude larger than the amount of desorbed I2. Model calculations were carried out that take into account laser photolysis of IBA, diffusion, and surface evaporation of I and I2, and the condensed-phase kinetics of radical reactions. Ejection of hyperthermal I atoms by direct photodissociation of surface layer molecules is also considered. The quantitative analysis is restricted to low laser fluence conditions at which laser-induced heating of the illuminated liquid is negligible. The results of the model calculations were compared to previously obtained TOF data of an alkyl iodide (C18H37I) dissolved in the apolar liquid squalane (C30H62). The velocity distribution of the iodine atoms from the alkyl iodide solution corresponds to the temperature of the liquid (278 K). The contribution of I atoms from depths greater than 1 nm is large (>99%). In contrast, I atoms desorbing from IBA/glycerol are hyperthermal (Ttrans=480 K) and originate almost exclusively from the topmost molecular layer (1 nm). TOF measurements with a fast chopper wheel in front of the surface provide the time-dependent desorption flux from the surface and confirm that the contribution from deeper layers in the alkyl iodide solution is much larger than in the aryl iodide solution. Model calculations predict the behavior of the two solutions correctly if differences in caging of the geminate pair, diffusion coefficients of the free radicals, and the set of bulk radical reactions in the two solutions are taken into account. The hyperthermal energies of the ejected I atoms from the IBA solution are discussed in terms of the surface orientation of excited IBA molecules. The dependence of the TOF spectra on laser power and IBA concentration is interpreted by a surface excess of IBA. The result is compared to temperature-dependent surface tension measurements of IBA solutions in glycerol and water. The response of the surface tension to an accumulation of IBA at the surface is very weak.

Biohazards and chemical hazards as well as radioactive hazards have always been a threat to human health. The search for solutions to these problems is an ongoing worldwide effort. In order to control biohazards by chemical methods, a synthetically useful fused tricyclic iodine-rich compound, 2,6-diiodo-3,5-dinitro-4,9-dihydrodipyrazolo [1,5-a:5′,1′-d][1,3,5]triazine (5), with good detonation performance was synthesized, characterized, and its properties determined. This compound which acts as an agent defeat weapon has been shown to destroy certain microorganisms effectively by releasing iodine after undergoing decomposition or combustion. The small iodine residues remaining will not be deleterious to human life after 1 month.
