Kinetics of Oxidation of Carbonyl Compounds by Peroxomonosulfate. Acetaldehyde, Propionaldehyde, and Butyraldehyde
Authors: Ramachandran M S , Vivekanandam T S , Arunachalam V 
Published: July 2006

Abstract
A kinetic study of oxidation of acetaldehyde, propionaldehyde, and butyraldehyde by peroxomonosulfate (PMS) in the presence of H+ ion has been carried out. The reaction shows first order dependence each on [PMS] and [Aldehyde]. The reaction shows inverse first order over a particular concentration range of H+ ion and beyond that first order dependence is observed with respect to [H+]. The inverse hydrogen ion dependence on kobsd may be due to the higher reactivity of SO52− than HSO5− with aldehydes. The increase in kobsd with increase in [H+] beyond certain [H+] can be explained by the formation of protonated carbonyl compounds. The Taft’s plot gives ρ* value of ≈5.0 indicating that the reaction is nucleophilic substitution at the carbonyl carbon which then rearranges to products.

Abstract
5,10-Dimethyl-6,8-bisdehydropentatridecafulvalene 11, 10-methyl-6,8-bisdehydro-4,5-benzopentatridecafulvalene 12, 6,8-bisdehydro-4,5:10,11-dibenzopentatridecafulvalene 13, 5,10-dimethyl-6,8-bisdehydropentapentadecafulvalene 14, 7,12-dimethyl-8,10-bisdehydropentaheptadecafulvalene 15, and 7,12-dimethyl-8,10-bisdehy-dropentanonadecafulvalene 16 were synthesized through the reaction of the corresponding bisdehydroannulenones 1–6 with cyclopentadienide. The tropic nature of these pentafulvalenes is discussed on the basis of 1H NMR and electronic spectra as well as those of the corresponding heptafulvalene derivatives.
NMR and XPS Studies of Some Diselenocarbamates. Bond Switch in Bis(dimethylselenocarbamoyl) Triselenide
Authors: Kobayashi Keiji , Tukada Hideyuki , Kikuchi Koichi , Ikemoto Isao 
Published: July 2006

Abstract
The hindered rotation about the C–N bond in dimethyldiselenocarbamates Me2N–CSe–SeR has been investigated by variable temperature NMR spectroscopy. The barrier to the rotation was almost independent of the partial structure of R (R=–Me, –CSe–NMe2), being 19 kcal mol−1* at around 93 °C. However, for bis(dimethylselenocarbamoyl) triselenide (R=–Se–Se–CSe–NMe2) (1), no splitting of N-methyl signals was observed in the 1H and 13C NMR spectra at subambient temperature. The equivalence of the methyl groups is discussed in terms of the bond switch between C=Se and C–Se moieties. The existence of the bond switch in 1 was also suggested by the XPS studies; the binding energy of the four selenium atoms was found to lie between those of C=Se and –Se–types of the selenium atoms, indicating that 1 takes an intramolecular coordination structure rather than a linear triselenide structure in the solid state, thereby facilitates the bond switch in solution.
The Determination of a Small Amount of a Biological Constituent by the Use of Chemiluminescence. VI. The Flow-Injection Analysis of Protein Using a 1,10-Phenanthroline–Hydrogen Peroxide System
Authors: Hara Tadashi , Ebuchi Takashi , Arai Akihiro , Imaki Masakatsu 
Published: July 2006

Abstract
Since the catalytic activity of copper(II) for the chemiluminescent reaction between 1,10-phenanthroline and hydrogen peroxide decreased in the presence of protein, this phenomenon was applied to the determination of protein. The determination of protein was carried out by a flow-injection method, and the conditions for the determination of protein were established. The catalytic activity of copper(II) was enhanced by using an amino acid instead of the conventional biuret reagent. Similar calibration curves were obtained for human serum albumin, bovine serum albumin, human serum γ-globulin, bovine serum γ-globulin, and ovalbumin. According to the present flow-injection method using a chemiluminescent reaction, a small amount of protein could be conveniently and economically determined over a wide range of concentrations, 5.0×10−6 g dm−3–1.0×10−1 g dm−3 at the rate of about 20 samples per hour, with the detection limit of 250 pg as the injected amount and the coefficient of variation of 5.9% (n=9). The sensitivity of the present method was about 40 times that of the previous luminol-hydrogen peroxide system.
Synthesis of Gramicidin S (GS) Analogs, [3–4-δAva]–GS and [3–4,3′–4′-Bis(δAva)]–GS (δAVa=5-Aminovaleric Acid)
Authors: Sofuku Shosuke , Sugiyama Yasutaro , Muramatsu Ichiro 
Published: July 2006

Abstract
Gramicidin S (GS) analogs, [δAva3–4]–GS and [δAva3–4,3′–4′]–GS, were synthesized. Both of these peptides are analogs in which one or two l-leucyl-d-phenylalanyl residues of GS are replaced by one or two 5-aminovaleric acid residues. The CD spectrum of the mono-substituted analog has two troughs as that of GS. However, this analog showed almost no antimicrobial activity. Moreover, the di-substituted analog showed a CD spectrum that is ascribed to a random structure and had no antimicrobial activity.
Reaction of Reduced PQQ (PQQH2) and Molecular Oxygen
Authors: Itoh Shinobu , Ohshiro Yoshiki , Agawa Toshio 
Published: July 2006

Abstract
Reduced PQQ (PQQH2) is prepared by the reaction of PQQ with thiophenol, 1-benzyl-1,4-dihydronicotinamide (BNAH), sodium dithionite, or sodium borohydride. Oxidation of PQQH2 to PQQ by molecular oxygen in aqueous solutions is investigated kinetically. The oxidation is accelerated gradually with proceeding of the reaction, which may be attributed to the side reaction of PQQH2 and H2O2 produced by the reaction of PQQH2 and O2. As in fact, the yield of H2O2 is found to be 50% based on PQQH2. Initial rate is first-order in oxygen concentration. The pH-rate profile suggests that an active species in the reaction is PQQH−. Autocatalysis of O2\ewdot and PQQ itself is scarcely detected in this reaction. The mechanism of the oxidation is also discussed.
Motions of Tetramethylammonium Cations and Phase Transitions in Solid [(CH3)4N]2CdX4 (X=Cl, Br, I) as Studied by 1H NMR, Powder X-Ray Diffraction, and Differential Thermal Analysis Measurements
Authors: Sato Setsuko , Ikeda Ryuichi , Nakamura Daiyu 
Published: July 2006

Abstract
The temperature dependences of 1H spin-lattice relaxation times were determined at 20 MHz for [(CH3)4N]2CdCl4, [(CH3)4N]2CdBr4, and [(CH3)4N]2CdI4. For the last two complexes, the frequency dependence of the relaxation time was observed above room temperature. 1H NMR second moments were observed for the bromide complex. At room temperature, the first two complexes were found to be isomorphous with the iodide complex which forms orthorhombic crystals. Differential thermal analysis experiments revealed that these complexes undergo four, one, and one solid-solid phase transitions in the above order between ca. 80 and 430 K. Two 1H T1 minima were clearly observed at lower temperatures for the chloride and bromide complexes, whereas at least three 1H T1 minima partly overlapped with each other were detected at lower temperatures for the iodide complex. For the former two complexes, the 1H T1 data were well analyzed by the general method already reported. For the bromide and iodide complexes, 1H T1 curves observed showed a maximum above room temperature. Motions of the cation activated in these complexes are discussed in relation to the crystal field experienced by the cation.

Published: July 2006

Abstract
Oxidative addition of (chloroformyl)ferrocene to [Pd(PPh3)4] yielded a stable acylpalladium(II) compound of [Pd(COFc)Cl(PPh3)2] (1), (Fc=ferrocenyl). Complex 1 was treated with alkali metal salts of poly(1-pyrazolyl)borates (HnBPz4−n), (Pz=1-pyrazolyl) to give complexes [Pd(COFc)(HnBPz4−n)(PPh3)], (2, n=0; 3, n=1; and 4, n=2), which retained the palladium-attached ferrocenylcarbonyl structure. Reaction of 1 with 1,10-phenanthroline (phen) afforded [Pd(COFc)Cl(phen)], whereas reaction with 2,2′-bipyridine gave [{Pd(COFc)Cl(PPh3)}2] as an isolable material. Transformation of the ferrocenylcarbonyl moiety took place to the ferrocenyl group on palladium, in chlorine-abstraction from 1 with AgClO4·H2O in CH3CN. In the temperature-dependent 1H-NMR spectra, fluxional behavior was observed for the poly(1-pyrazolyl)borate groups in 2 and 3. Electrochemical experiments were carried out for 1–4 in CH3CN using platinum working electrodes, and reversible one-electron redox-couples were detected, which were attributed to the process Fe(II)\ightleftarrowsFe(III) in the ferrocenyl moiety. Furthermore, electron-withdrawing effects of the [poly(1-pyrazolyl)borato]palladiocarbonyl moieties from the Fe centers were compared among these complexes, in relation to their redox potentials.

Abstract
The coupling reaction of Grignard reagents with α,β-dibromoalkanes took place smoothly in THF/ HMPA (12:1) in the presence of a catalytic amount of copper(I) bromide and gave the products in 60–100% yields. Several α,ω-bis(vinylaryl)alkanes were prepared in reasonable yields by the application of this reaction.

Abstract
The crystal structures of the bicyclic oxalactam, 8-oxa-6-azabicyclo[3.2.1]octan-7-one(BOL) and the 4(e)-bromo-substituted derivative(Br–BOL) were determined by the X-ray diffraction method. Crystal data: (BOL) P212121, a=10.926(3), b=9.115(2), c=6.280(2), Å, Z=4; (Br–BOL) P212121, a=10.708(3), b=11.053(3), c=6.208(2), Å, Z=4. Refinements were carried out by the full-matrix least-squares method. R values are; (BOL) 0.050 for 601 reflections, (Br–BOL) 0.028 for 866 reflections. Both structures are quite similar to each other. The packing scheme of BOL is essentially the same as that of Br–BOL. Molecules are linked by N–H···O hydrogen bonds around a two-fold screw axis, giving rise to infinite chains extended along the c axis.

Bisdehydrodibenzo[14]-, -[16]-, -[18]-, -[20]-, and -[22]annulene were synthesized by intramolecular reductive couplings using a low-valent titanium reagent. These bisdehydrodibenzo-annulenes proved to be atropic from an examination of the 1H NMR spectra.
Active Carbon-Supported Copper(I) Chloride as Solid Adsorbent for Carbon Monoxide
Authors: Hirai Hidefumi , Wada Keiichiro , Komiyama Makoto 
Published: July 2006

Abstract
An active carbon-supported copper(I) chloride (CuCl) is prepared by stirring active carbon in aqueous hydrochloric acid solution of CuCl, followed by removal of the liquid phase under 6 mmHg at 100 °C. The resulting solid rapidly adsorbs carbon monoxide (CO) at 20 °C from 9:1 CO–N2 mixture under 1 atm (the CO partial pressure 0.9 atm) and the equilibrium molar ratio of adsorbed CO to CuCl is 0.88. All of adsorbed CO is promptly desorbed either by reducing CO partial pressure to 0.4 mmHg at 20 °C or by elevating temperature from 20 °C to 120 °C under 1 atm (the CO partial pressure 0.9 atm). Reversible adsorption-desorption cycles are repeated four times without measurable decrease in the adsorbing capacity. The adsorbing capacity of the active carbon-supported CuCl is much larger than either that of CuCl solid or that of active carbon. Effective CO adsorption by the present adsorbent is attributed to formation of complex between CO and CuCl, which is highly dispersed on the surface of active carbon.
Reactivity of Electrons Produced in Gamma-Irradiated Zeolite Toward Several Electron Scavengers
Authors: Nakazato Chiyoko , Masuda Takahiro 
Published: July 2006

Abstract
Relative rates of reaction of electrons produced in gamma-irradiated zeolite (Molecular Sieve 13X) with several electron scavengers were determined by competition kinetics using dinitrogen monoxide as a reference compound. A part of the electrons produced in irradiated zeolite have been disclosed to be quasi-free from the feature of their reactivity toward electron scavengers that the reactivity is similar to that of quasi-free electrons found in irradiated liquid 2,2-dimethylpropane. An analysis based on competition kinetics has provided a value 9.8×1012 dm3 mol−1 s−1 as the lower limit on the rate constant for the reaction of quasi-free electrons with positive holes produced in irradiated zeolite.
An EXAFS Investigation of the Coordination Structure of Copper(II) Ions in Aqueous Cu(ClO4)2 and Methanolic CuCl2 Solutions
Authors: Tajiri Yoshichika , Wakita Hisanobu 
Published: July 2006

Abstract
The coordination structure of copper(II) ions in aqueous and methanolic solutions was investigated by means of EXAFS spectroscopy. The hexaaquacopper(II) complex in the aqueous Cu(ClO4)2 solution had an elongated octahedral structure, with four equatorial distances of 2.00 Å and two axial distances of 2.28 Å. Scarcely no axial interaction has been seen in the radial-distribution curve after the Fourier transform of the EXAFS spectrum, for the real and imaginary parts of the Fourier transformed function for the axial interactions are diminished by the interference of those for the equatorial interactions. Two distances for the equatorial interactions of the mixed-ligand chlorocopper(II) complexes in the methanolic CuCl2 solution were clearly resolvable in the radial-distribution curve; they were 2.00 Å and 2.22 Å for the Cu–O and Cu–Cl interactions respectively.

Published: July 2006

Abstract
Synthesis of a cyclic sulfide moiety ring B in peptide antibiotic nisin was successfully achieved by desulfurization from a corresponding disulfide peptide with tris(diethylamino)phosphine. The configuration on β-carbon atom of threo-3-methyl-d-cysteineresidue in the disulfide peptide was retained through the reaction to give a desired natural threo form of methyllanthionine.

Authors: Sugahara Yoshiyuki , Kitano Shuichi , Satokawa Shigeo , Kuroda Kazuyuki , Kato Chuzo 
Published: July 2006

Abstract
Intercalation compounds of kaolinite with 2-pyrrolidone and 2-piperidone have been prepared for the first time by displacing other intercalates. 2-Pyrrolidone expanded the lattice of kaolinite to 11.9 Å, while d001 of 12.7 Å was observed with the kaolinite–2-piperidone intercalation compound. Their IR spectra indicated the formation of a hydrogen bond between the C=O of the lactams and the OH of kaolinite. Nevertheless, their interactions were different between these two intercalation compounds. By a comparison of their behaviors, it has been concluded that the kaolinite–2-pyrrolidone intercalation compound is thermally more stable than the kaolinite–2-piperidone intercalation compound.
Temperature Dependence of 35Cl Nuclear Quadrupole Resonance Frequencies and Hydrogen Bonding in Some Metal(II) Hexachlorostannate(IV) Hexahydrates
Authors: Horiuchi Keizo , Sasane Akinobu , Mori Yoshihiro , Asaji Tetsuo , Nakamura Daiyu 
Published: July 2006

Abstract
The temperature dependences of 35Cl NQR frequencies were observed over a fairly wide range of temperature for MSnCl6·6H2O [M(II)=Mg, Ca, Mn, Co, Ni] forming isomorphous crystals (R\bar3) at room temperature. These complexes yielded unusual 35Cl NQR temperature dependence curves showing a positive temperature coefficient. This can be attributed to the existence of Cl···H–O type weak hydrogen bonds.
The Structure of Liquid N-Methylformamide by Means of X-Ray Diffraction and Ab Initio LCGO–MO–SCF Calculations
Authors: Ohtaki Hitoshi , Itoh Sumiko , Rode Bernd M 
Published: July 2006

Abstract
The liquid structure of N-methylformamide (NMF) has been investigated by the X-ray diffraction method and the ab initio MO-SCF method. The structure parameters within a molecule were obtained as follows: C=O : 122(1) pm, C(methyl)–N : 145(2) pm, C(carbonyl)–N : 134(2) pm, N···O : 222(4) pm, C(methyl)···O : 278(6) pm. The intermolecular hydrogen–bonded N···O distance was estimated to be 298(11) pm. A linear and flexible chain structure was proposed for the liquid structure of NMF on the basis of scattered intensity data by the X-ray diffraction method and of interaction energies and geometries of hydrogen-bonded NMF molecules calculated by the ab initio MO calculations.
Proton Transfer Reactions in the Triplet State of Benzophenone Studied by Nanosecond Laser Flash Photolysis
Authors: Hoshi Masahiko , Shizuka Haruo 
Published: July 2006

Abstract
Proton-transfer reactions in the triplet state of benzophenone in H2O–acetonitrile (4:1) at 20 °C have been studied by means of nanosecond nitrogen laser flash photolysis at 337 nm. The proton association (k1) and dissociation (k2) rates are determined to be 5.0 (±0.5)×109 mol−1 dm3 s−1 and 3.3 (±0.3)×109 s−1 respectively by a transient kinetic treatment. These rates are large enough to make an acid-base equilibrium during the lifetime of the triplet state. The acidity constants (pKa*) in the triplet state of benzophenone obtained by the transient kinetic treatment, the Ware plot, and the Tn←T1 absorbance titration curve are the same [0.18 (±0.1)]. The pKa* value determined by the titration method is appreciably dependent upon the delay time after the start of pulsing (the accurate value was obtained at the delay time 20 ns). There is no proton-induced quenching in the triplet state of benzophenone, since electrophilic protonation occurs at the oxygen atom in the carbonyl group. The reactive state for protonation in the triplet state is not 3(n,π*), but 3(π,π*), judging from the large k1 value and the pKa* value.
Electrocatalytic Oxygen Reduction at (Tetrasulfonatophthalocyaninato)cobalt Incorporated Polypyrrole Film Electrode
Authors: Osaka Tetsuya , Naoi Katsuhiko , Hirabayashi Takayuki , Nakamura Sadako 
Published: July 2006

Abstract
Electrocatalytic activity of oxygen reduction was strikingly improved at a GC(glassy carbon)/PPy(polypyrrole)/CoTSP((tetrasulfonatophthalocyaninato)cobalt) electrode among the other CoTSP doped polymer electrodes. The GC/PPy/CoTSP electrode was formed by electro-oxidized polymerization of pyrrole on a glassy carbon(GC) electrode in methanol solution containing CoTSP. The catalytic oxygen reduction at the GC/PPy/CoTSP electrode was mainly analyzed with RRDE technique. Oxygen reduction reaction at the GC/PPy/CoTSP electrode in 0.05 mol dm−3 H2SO4 showed ca. 0.5 V more anodic onset potential than the value obtained with a GC electrode in 0.05 mol dm−3 H2SO4 containing 10−3 mol dm−3 CoTSP. Kouteckty-Levich plot, i.e., the relation between Ilim−1 and ω−1⁄2 for the GC/PPy/CoTSP electrode gave almost the same slope of theoretical four-electron reduction at the limiting current region. It was indicated that the apparent oxygen reduction is occurred through direct four-electron exchange process. On the other hand, the GC electrode in dissolved CoTSP gave almost the same slope as of theoretical two-electron reduction. A diagnostic criterion for oxygen reduction proposed by Wroblowa et al. indicated that the parallel pathways of two- and four-electron reduction exist for the GC/PPy/CoTSP electrode.
Synthesis and Electrical Conductivity of a New Family of Pt Mixed Valence Complexes: Pt6(NH3)14Cl10X4 (X=ClO4, BF4, and PF6)
Authors: Tanaka Masako , Tsujikawa Ikuji 
Published: July 2006

Abstract
A new family of Pt mixed valence complexes: Pt6(NH3)14Cl10X4 (X=ClO4, BF4, and PF6) was synthesized from the Magnus green salt (MGS) by the partial oxidation using an oxidant of H2O2 or by electrochemical method. On partial oxidation, the 1/6 of Cl− ligands in MGS are randomly replaced by NH3 ligands and simultaneously counter ions X are introduced. These complexes comprise of one-dimensional chains with direct contact between Pt atoms and consequently a quasi-one-dimensional band made up of 5dz2 orbital of Pt is formed. The average valence of Pt is +2.33 and the distance between Pt atoms along a chain is shorter than or comparable to that of K2[Pt(CN)4]Br0.3·xH2O (KCP). The electrical conductivity σ of these complexes was measured from 80 K to r.t. The σ(r.t.) is rather high in spite of the measurement on the powder pressed pellets. This suggests that σ along a chain direction may be as high as that of KCP if single crystals can be obtained. The conductivity data were fitted using a gap energy with various temperature dependence. In the complex with X=PF6, there may be a phase transition caused by ordering of PF6− ions at about 110 K.

Abstract
A series of 10-substituted tricyclo[5.3.1.02,6]undeca-3,9-dien-8-ones (6) and the 4,9-dien-8-one isomers (7) were synthesized and photolyzed. Upon irradation, whereas most of the derivatives underwent [2+2] photocyclization to give the corresponding novel trishomocubanones, the methyl and phenyl derivatives of 7 afforded products attributable to intramolecular hydrogen abstraction by the β-carbon of the α,β-unsaturated ketone along with the photocyclization products.

Published: July 2006

Abstract
Oxygen content of SnO2 and Zn2SnO4 crystals grown by the vapor phase method was determined by 14 MeV neutron activation analysis. The oxygen contents in the crystals were a little smaller than the theoretical values. The oxygen deficiency in the crystals was found to be related to their inherent semiconductive properties and density.

Published: July 2006

Abstract
The microwave spectrum of (Z)-(propionaldehyde oxime) was observed in the frequency region of 10 to 30 GHz. The rotational constants (MHz) for the ground vibrational state were determined to be A=15453.95±0.20, B=2733.60±0.03, and C=2394.85±0.02. The conformation has been plausibly deduced to be the ap, Z-form from the rotational constants. The dipole moments were determined by the Stark effect: μa=0.889±0.010 and μb=0.364±0.025 D.
