Authors: Ohtaki Hitoshi , Maeda Masunobu , Ito Satoshi 
Published: July 2006

Abstract
X-Ray diffraction measurements were carried out for aqueous solutions of cadmium perchlorate and sodium tetraiodocadmate. X-Ray scattering data showed that the hydrated Cd2+ ion is coordinated to six water molecules, the distance between Cd2+ and H2O being 2.31±0.02 Å, and that the CdI42− complex has a tetrahedral configuration with a Cd–I distance of 2.79±0.01 Å. The tetrahedral structure of the CdI42− complex was confirmed by Raman spectroscopy.
Polarographic Study of Catalytic Reduction of Tris(2,2′-bipyridine)-copper(II) in the Presence of Nitrite Ion
Authors: Tanaka Kazuyoshi , Nakano Kunio 
Published: July 2006

Abstract
The rigorously derived equation for a catalytic current was applied to the evaluation of the rate constant for the oxidation reaction of bis(2,2′-bipyridine)copper(I) by nitrite ion by use of a computer and subroutine program for the curve-fitting method. This method made it possible to calculate the rate constant from low limiting current in the presence of nitrite ion. The rate in acetate buffer solutions has first-order dependence on each reactant and hydrogen ion, and the apparent rate constant is 1×106 M−2 s−1 at 25 °C.

Authors: Maeda Masunobu , Ohtaki Hitoshi , Johansson Georg 
Published: July 2006

Abstract
The structures of the AuCl4− and the AuBr4− complexes in aqueous solutions have been determined from X-ray scattering measurements on concentrated solutions of tetrachloroauric and tetrabromoauric acids. Both the tetrachloroaurate(III) and the tetrabromoaurate(III) complexes were found to have a square planar symmetry. The values obtained for the interatomic distances within the complexes are: Au–Cl, 2.291 Å; cis-Cl–Cl, 3.24 Å; trans-Cl–Cl, 4.58 Å; Au–Br, 2.432 Å; cis-Br–Br, 3.44 Å; trans-Br–Br, 4.86 Å.
Atomic Absorption Spectrophotometric Determination of Rare Earths (Y, Eu, Gd, Dy, Ho, and Er) in Single Crystals of Magnetic Garnets and Sulfides
Authors: Ametani Kohei 
Published: July 2006

Abstract
Atomic absorption spectrophotometric studies were carried out on single-crystal rare-earth magnetic garnets, (R1R2)3(Fe,Ga)5O12, where R1 and R2 are Y, Eu, Gd, and Er, and sulfides RCr3S6, where R is Y, Gd, Dy, Ho, and Er. A method using lanthanum chloride to suppress the interference effects of other elements was demonstrated for the atomic-absorption determination of rare earths. Lanthanum chloride is much better than alkaline metal chlorides (NaCl, KCl, and CsCl) and chelating agents (EDTA·2Na and EDTA·2NH4) for removing the interference effects of foreign elements from the yttrium measurement. Similar results with lanthanum chloride are observed with other rare earths. Experimental results for various samples are also presented. The present method has been utilized for several years in our laboratories to analyse rare earths in newly prepared materials.
Photochemical Reactions of Some 1-Aryl-1,2-propanediones
Authors: Ogata Yoshiro , Takagi Katsuhiko 
Published: July 2006

Abstract
Irradiation of four 1-aryl-1,2-propanediones (Ia–Id) with over 300 nm light in 2-propanol gives reduction products identified to be the corresponding pinacols or hydrols formed by the reduction at the aroyl (but not acetyl) oxygen. The products from 1-(o-tolyl)-1,2-propanedione (Id) can also be accounted for by the initial hydrogen abstraction from ortho methyl by the aroyl carbonyl oxygen. Their photoreactivities are discussed as regards their electronic emission spectra and triplet configuration.
Sulfur-containing Polymers. XIII. The Synthesis and Properties of Soluble Polydithiocarbamates
Authors: Kobayashi Norio , Osawa Akiko , Fujisawa Tamotsu 
Published: July 2006

Abstract
Polydithiocarbamates have been synthesized by the polycondensation of di-K or di-Na bisdithiocarbamates based on secondary diamines with bischloromethylated aromatics in N,N-dimethylformamide. The polymers obtained in good yields had inherent viscosities up to 0.66. The polymers derived from 1,3-di-4-piperidylpropane were soluble in organic solvents, such as dichloromethane and chloroform, and gave transparent, tough films from the solution. These polymers decomposed upon UV irradiation, with the liberation of carbon disulfide. The photopolymerization of methyl methacrylate in the presence of the polymer has also been studied.
Nucleosides. XXI. Preparative Routes to Nucleosides Derived from 4-Amino-4-deoxy-β-d-glucopyranose
Authors: Lichtenthaler Frieder W , Voss Peter , Bambach Gerd 
Published: July 2006

Abstract
Four-step syntheses for the 4′-arnino-4′-deoxy-β-d-glucopyranosyl nucleosides of adenine (7), uracil (12) and cytosine (16) from a readily accessible galactose derivative (2) are described, in overall yields of 41–47%. The reaction sequence, used, involved (i) stannic chloride catalyzed nucleosidations of 2 with the bis-trimethylsilyl derivatives of N6-benzoyladenine, uracil and N4-acetylcytosine, (ii) displacement of the 4′-sulfonyloxy groups in 3, 10, and 15 by azide, (iii) de-O-benzoylation and (iv) hydrogenation. An alternate route to 12 and 16, comprising nucleosidation of tetraacetyl-4-acetamido-4-deoxy-d-glucopyranose (20) via the classical Hilbert-Johnson approach proved feasable, yet inferior with respect to yields and accessibility of educts. The structures and configurations assigned followed from the synthetic route as well as from spectroscopic data, particularly from the acetyl resonances of the peracetylated nucleosides 9, 14, and 18, which are in excellent agreement with those of the respective glucosyl- and 3-acetamido-3-deoxy-glucosyl analogs (Table).
Nucleosides. XXII. Pyrimidine Nucleosides of 4-Amino-4-deoxy-β-d-galactopyranose
Authors: Lichtenthaler Frieder W , Ueno Tamio , Voss Peter 
Published: July 2006

Abstract
In a four step sequence from 1-O-acetyl-2,3,6-tri-O-benzoyl-4-O-mesyl-α-d-glucose (4), 4′-amino-4′-deoxy-β-d-galactosyl-cytosine (1) was synthesized, involving stannic chloride catalyzed nucleosidation with bis(trimethylsilyl)-N4-acetyl-cytosine, azidolysis of the 4′-sulfonyloxy group, deblocking and reduction (overall yield: 48%). An alternate, though preparatively less satisfactory approach was used for the preparation of the uracil analogue 2, which started from β-d-glucosyl-cytosine or uracil (9 or 15) and proceeded via standard blocking and deblocking reactions to the 4′-O-mesylglucosyl-uracil (20) and was concluded by azidolysis (20, 21), removal of protecting groups and reduction. Structural and configurational assignments evolved from the mode of preparation as well as from spectroscopic data, most conveniently from the acetyl resonances of the peracetylated nucleosides 8 and 24, which are in accord with those of their galactosyl and 3-acetamido-3-deoxy-galactosyl counterparts (Table).

Published: July 2006

Abstract
In the adsorption of aniline derivatives on Pt electrode, a linear relation was observed between the chemical shift of the m- and p-amino protons and the inhibiting effect on the anodic oxidation of methanol. However, o-alkylanilines and chloroanilines showed deviations due to steric hindrance and strong interactions, respectively.

Authors: Otsuka Kiyoshi , Morikawa Akira 
Published: July 2006

Abstract
The triplet-triplet energy transfer from ketones adsorbed on the Vycor glass to 2-butenes was rapid enough for us to neglect the transfer to the surface when the transfer is exothermic. Different photoisomerization mechanisms were suggested for different groups of sensitizers.

Abstract
The B–I distance of BI3 was determined to be 2.118±0.005 Å. A modified Schomaker-Stevenson rule holds for the boron-halogen bond lengths of the boron trihalides except for the fluoride. The B–F distance is much shorter than the value predicted by the rule.

Published: July 2006

Abstract
The distribution coefficients of Ag+, Tl+, K+, NH4+, Mg2+, Ca2+, Sr2+, Ba2+, Co2+, Zn2+, Y3+, and Ce3+ have been determined on a crystalline zirconium phosphate ion-exchanger in chloride solution media, and the affinity sequences are presented. pH titration curves and X-ray powder diffraction data were obtained for calcium and barium ions. The ion-exchange capacity of the exchanger for barium ions was found to be 4.4 meq/g, but the X-ray powder patterns were rather unusual as compared to those of other ions studied previously.

Abstract
Some binuclear and trinuclear complexes containing μ-l-aminocarboxylato ligands, (+)d- and (−)d-[en2-Co(OCOCH(NH2)(CH2)nCOO)Co(OH2)en2](ClO4)4, (+)d-[en2Co(OCOCH(NH2)(CH2)nCOO)Co(NH3)5]-(ClO4)4 and (+)d- and (−)d-[en2Co{(OCOCH(NH2)(CH2)nCOO)Co en2}2](ClO4)5 (n=1 for l-aspartato and n=2 for l-glutamato), have been newly prepared. The structure and vicinal CD effect of these complexes were discussed on the basis of their absorption, 13C NMR and CD spectra data. Their geometrical structures were assigned as cis to the μ-l-aminocarboxylato-OH2 binuclear complexes (with respect to the β-COO or γ-COO end of μ-aminocarboxylato bridge and the aquo ligand), and as trans to the di-μ-l-aminocarboxylato trinuclear complexes (with respect to the β-COO or γ-COO ends of two μ-aminocarboxylato bridges).

The One-electron Reduction of Carbonium Ions. VII. A Kinetic Study of the Reduction of the Aryl- and n-Alkyl-substituted Tropylium Ions with Cr(II)
Authors: Okamoto Kunio , Komatsu Koichi , Fujimori Masami , Yasuda Sumio 
Published: July 2006

Abstract
A series of substituted phenyltropylium (I) and n-alkyltropylium ions (II) has been synthesized, and the kinetic measurements for the one-electron reduction of these ions have been carried out with Cr(II) in 10% HCl at 25°C. A linear correlation is observed between the logk2 values, for I (X-C6H4-C7H6+, X=p-OH, p-OCH3, p-CH3, H, p-Cl, p-Br, p-CN, m-OCH3) and for II (CnH2n+1-C7H6+, n=0,1–6), and the transition energy of the charge-transfer band of these ions, with pyrene as a donor. In addition, the values of logk2 for I exhibit a good linear free-energy relationship with pKR+ and also with the σ -value (ρ=+1.31), but not with σ+. The n-alkyl group is shown to diminish the reducibility of the tropylium ion, and a slight alternation effect of the length of the n-alkyl chain on the K2’s is observed.
The One-electron Reduction of Carbonium Ions. VIII. The Reducibility of Hetero-substituted Tropylium Ions as Measured by the Competitive Reduction Method with Zinc Powder
Authors: Okamoto Kunio , Komatsu Koichi , Sakaguchi Osamu 
Published: July 2006

Abstract
A series of hetero-substituted tropylium salts (X-C7H6+·Y−), including three new compounds, have been synthesized. Their relative reactivities in one-electron reductions with zinc powder have been determined by the use of a competitive-reaction method, which gave the following reactivity sequence: CH3O-C7H6+ (krel.=0.0295), t-C4H9-C7H6+ (0.146), CH3S-C7H6+ (0.255), C7H7+ (1.00), C6H5-C7H6+ (2.50), (C6H5)3Si-C7H6+ (7.50), Cl-C7H6+ (16.8), CH3OCO-C7H6+ (35.7), NC-C7H6+ (163). The values of logkrel. for the t-C4H9−, H-, and C6H5-C7H6+ ions exhibit a good linear relationship with those of logk2 in the chromous-ion reduction. A linear correlation is also observed between logkrel. and the transition energy for the charge-transfer band of the respective cations, with pyrene as a donor. A plot of logkrel. against σp (for the ring substituent, X) gives a greater ρ-value (+4.0) than in the case of X-C6H4-C7H6+ (+1.31), reflecting the influence of the direct substitution on the tropylium ring.

Authors: Takeshita Hitoshi , Mori Akira , Ohta Shumei 
Published: July 2006

Abstract
Singlet oxygen was allowed to react with three 3-hydroxypyridine derivatives, I, II, and III, in order to investigate its general behavior toward dipolar substrates. The occurrence of an easy C=C cleavage process to give furanones (V and XI) through the dioxetones was a characteristic feature. In addition, maleimides (IV and IX), oxamates (VIII, XII and XIV), and a carbamate (XIII) were isolated as highly oxidized products.

Authors: Nagayama Masuzo , Okumura Osamu , Yaguchi Katsumi , Mori Akira 
Published: July 2006

Abstract
2-Dimethylsulfonioalkane-1-sulfonates were formed by the reaction of α-olefins with the dimethyl sulfide-sulfur trioxide complex. The treatment of these products with alkali gave Δ1-alkene-1-sulfonates quantitatively. In the reaction between 1,2-epoxyalkanes and the dimethyl sulfide-sulfur trioxide complex, 1-dimethylsulfoniomethyl-1-alkyl sulfate was formed exclusively. 1-Dimethylsulfonio-1-alkenes were quantitatively formed upon the treatment of these products with alkali. The chemical structures of these compounds have been established, and the reaction routes were discussed.
Fourier Analysis of AC Polarography. Elimination of Non-Faradaic Effects and Determination of Kinetic Parameters for Cd(II)-Na2SO4 System
Authors: Hirota Michio , Umezawa Yoshio , Kojima Hiroyuki , Fujiwara Shizuo 
Published: July 2006

Abstract
The on-line Fourier analysis of the AC polarographic current was found to give accurate results for electrode kinetics provided that the compensation of the iR drop and of the non-faradaic current was attained: The iR drop was compensated by a positive feedback technique. The charging current was cancelled by addition of a pseudo-charging current, inverse in phase to the former. Both the phase angles and amplitudes of the fundamental and second harmonic AC responses for the system of Pb(II) in 1M NaClO4 ([H+]=12 mM) agreed with theoretical prediction. As an illustration, the kinetic parameters of Cd(II)-1 n Na2SO4 system have been determined to be ks=(0.20±0.03) cm/s and α=0.30 (0.27&lt;0.30&lt;0.35) from the second harmonic AC polarogram.
A Polarographic Study of the Dissociation Reactions of the Ethylenediaminemonoacetatocobalt(II) (Co(II)-EDMA) and Ethylenediaminediacetatonickel(II) (Ni(II)-EDDA) Complexes
Authors: Kodama Mutsuo 
Published: July 2006

Abstract
The rates and the mechanisms of the dissociation reactions of the Co(II)-EDMA complex in a phosphate buffer solution and the Ni(II)-EDDA complex in an ethylenediaminediacetate solution were studied by analyzing their kinetic waves by means of conventional DC polarography. The dissociation of the Co(II)-EDMA complex gave this rate law: −d[Co(II)-EDMA]⁄dt=kp·[Co(edma)+]·[H2PO4]−. On the other hand, the dissociation of the Ni(II)-EDDA complex was found to proceed through a reaction mechanism which involves ligandolysis, corresponding to this rate law: −d[Ni(edda)0]⁄dt=k0×[Ni(edda)0]. On the basis of the relative rate constant, the detailed reaction mechanism was discussed. In the dissociation of the Co(II)-EDMA complex, the phosphate anion acts just as a proton donor. In the case of the Ni(II)-EDDA complex, the ligandolysis of the coordinated water has a profound effect on the dissociation rate of the edda2− anion from the nickel (II) ion.

Published: July 2006

Abstract
The reactions of norbornadiene in amine by the use of nickel, palladium and rhodium complexes have been studied in the presence of protic acid. A catalytic system of Ni(COD)2 (1)-n-Bu3P gives a mixture of 5-exo-(o-tolyl)-2-norbornene (3) and 5-exo-(N-amino)-2-norbornene (4). Bis(triphenylphosphine)(maleic anhydride)palladium (5) gives 3-(N-amino)nortricyclene (6). Dichlorotetrakis(cyclooctene)dirhodium (10) gives a [2+4] cycloaddition product (11). All these reactions mechanisms are discussed from the point of view of an acid-promoted reaction on low-valent transition metal complexes.
X-Ray Photoelectron Spectroscopic Study of the Reaction of Evaporated Iron, Nickel, and Palladium with Nitric Oxide
Authors: Kishi Kosaku , Ikeda Shigero 
Published: July 2006

Abstract
The reaction of the evaporated iron, nickel, and palladium with NO was investigated by X-ray photoelectron spectroscopy. On both iron and nickel larger part of NO dissociates to give two or more N(1s) and O(1s) photoelectron peaks which are ascribable to the surface oxide, nitride, and NO species. The proportion of these species is estimated roughly from the intensity ratios of the N(1s) and O(1s) peaks at 15 NO: 65 O: 20 N (iron) and 7 NO: 65 O: 28 N (nickel) when the metals are exposed to 5 Torr of NO gasfor 1 s, and 35 NO: 55 O: 10 N (iron) and 10 NO: 75 O: 15 N (nickel) when exposed to 10 Torr of NO for 10 min. On palladium the N(1s) for chemisorbed NO is observed. The N(1s) binding energies of the surface NO are compared with the N(1s) binding energies and the infrared NO frequencies of the corresponding transition metal nitrosyls.
The Equilibria for the Inosine–Calcium Hydroxide–Water and Inosine–Strontium Hydroxide–Water Systems
Authors: Suzuki Yoshihisa , Nomura Yasuichi 
Published: July 2006

Abstract
Solubility data have been obtained for the inosine–Ca(OH)2–H2O and inosine–Sr(OH)2–H2O systems at 10 °C. Three different solid phases of the calcium salt of inosine were found in the former system. The first is the normal hemi-calcium salt, (inosine) 2·Ca·2H2O; the second, an abnormal salt, (inosine)3·Ca·3H2O, and the third, another abnormal salt, (inosine)4·Ca·9H2O. The former two salts have stable regions in the system, while the last one does not. The system including Sr(OH)2 is simple, and no other salt-formation was found except for that of normal hemi-strontium salt, (inosine)2·Sr·2H2O. The X-ray powder diffraction data of the above four salts are given. The solubilities of the two normal hemi-alkaline-earth-metal salts of inosine in water were determined at 10—60 °C and formulated as follows:
Ca-salt, logS & = 0.00406·t - 0.4725
Sr-salt, logS & = 0.00551·t - 0.4116
where S represents the gram weight of anhydrous salt per 100 g of water.
