Palladium(II) Sulfate-Heteropoly Acid-catalyzed Oxidation of Cycloolefins in Liquid Phase
Authors: Ogawa Haruo , Fujinami Hideharu , Taya Kazuo , Teratani Shousuke 
Published: July 2006

Abstract
Heteropoly acid (HPA) was used as an oxidant in the Wacker catalyst system. Among the catalyst systems examined, the PdSO4–H3PMo6W6O40 catalyst system showed the highest activity with regard to the oxidation of cycloolefins, particularly cyclopentene and cyclohexene, to the corresponding cyclic ketones. The largest total turnover number with respect to Pd2+ was found to be 85 in water containing 20% N-methylformamide by volume. The initial rate of cyclohexene oxidation was expressed as
V o=k[Cyclohexene]1.0[PdSO4]1.0[HPA]0[O2]0.
The rate-determining step was suggested as being where cyclohexene was oxidized to cyclohexanone by Pd(II) salt. The apparent activation energy was 7.8 kcal mol−1 (1 cal=4.18 J). In the catalytic oxidation of cycloolefins (CnH2n−2: n=5, 6, 7, and 8), the yield of alicyclic ketone decreased as the carbon number n increased. Methyl-substituted cyclohexenes exhibited lower reactivities than cyclohexene.

Published: July 2006

Abstract
The reaction of biphenylene with Pb(OAc)4 gave 2-substituted biphenylenes and 2,3-biphenylenedione. The reaction of 2-methylbiphenylene and 2,3-dimethylbiphenylene with Mn(OAc)3 yielded products in which the methyl substituent had been oxidized. The reaction of 2-methoxybiphenylene with Pb(OAc)4 gave 2-acetoxy-3-methoxybiphenylene and r-2,c-3-diacetoxy-2-methoxy-2,3-dihydrobiphenylene, which is the first example of a 2,3-dihydrobiphenylene. The reactions of 2-carboxy-, 2-methoxycarbonyl- and 2,7-dibromobiphenylene with Mn(OAc)3 and (in part) with Pb(OAc)4 yielded nuclear acetoxymethylated products. The conversion of r-2,c-3-diacetoxy-2-methoxy-2,3-dihydrobiphenylene into 5,10-diacetoxy-7(8H)-benzocyclooctenone was observed.

Published: July 2006

Abstract
The copper-promoted Ullmann reaction of chiral diol diesters of 1-bromo-2-naphthoic acid induced axial dissymmetry into the newly formed 1,1′-binaphthyl bond: chiral diol, apparent net optical yield for the joining of two naphthyl units, and axial chirality induced are as follows: (S)-1,1′-binaphthyl-2,2′-diol, 71%, S; (1S,2S)-1,2-diphenyl-1,2-ethanediol, 32%, S; (1R,2R)-1,2-bis(ethoxycarbonyl)-1,2-ethanediol, 33%, S; (4S,5S)-bis(hydroxymethyl)-2,2-dimethyl-1,3-dioxolane, 3.7%, R. The reaction of (R)-1,1′-binaphthyl-2,2′-diol esters of 2-halo-3-nitrobenzoic acids gave up to 85% net optical yield for the coupling; the intramolecular cyclization proceeded with virtually complete diastereoselectivity to give cyclic diester of R,R-configuration in a 42% isolated yield. This remarkable stereocontrol is ascribed to the steric requirement of the 12-membered cyclic diester structure containing rigid 1,1′-binaphthyl and 1,1′-biphenyl moiety.
The Synthesis of Li+-selective Polyether Carriers and Thier Behavior in Cation Transport through Liquid Membranes
Authors: Hiratani Kazuhisa , Taguchi Kazuhiro , Sugihara Hideki , Iio Kokoro 
Published: July 2006

Abstract
Noncyclic polyethers exhibiting lithium ion selectivity have been synthesized. Their competitive alkalimetal-ion transport through liquid membranes has been investigated, and the influence of their structures on the rates and selectivities of cation transport has been demonstrated. It has been found that the introduction of the oxytrimethylene chain on the polyethers is significant for the appearance of a high selectivity for the lithium ion, and also that the kind of terminal group might play an important role either in determining the rates of cation transport or the selectivity for the lithium ion. The introduction of a methyl group at the 2-position on the quinolyl terminal group of the polyether increased largely the selectivity for the lithium ion compared with that of the polyether having an unsubstituted quinolyl group. The cause of this was discussed on the basis of the NMR spectroscopic method and the CPK-model building.

Authors: Uchida Tokiko , Kozawa Kozo , Saito Takao , Motoki Shinichi 
Published: July 2006

Abstract
The crystal and molecular structures of the title compound were determined by means of X-ray diffraction. Crystal data: C16H18NS2P, Mr=319.4, triclinic, a=12.731(2), b=13.143(1), c=12.483(1) Å, α=102.39(1), β=104.34(1), γ=117.96(1)°, V=1648.6 Å3, space group P\barl, Dm=1.30, Dx=1.287 g cm−3, Z=4, μ=4.02 cm−1 (Mo Kα). The structure was solved by the direct method and refined by the block-diagonal least-squares method to R=0.082 for 4495 observed reflections. The bond distances and angles are in good agreement with the ordinary values except for the P–S–C bridged angle of 82.5°. An asymmetric unit contains two crystallographically independent molecules, which are rotational isomers along the P–C bond.
A Convenient Method for the Regioselective Synthesis of 4-Alkyl(aryl)pyridines Using Pyridinium Salts
Authors: Akiba Kin-ya , Iseki Y\={u}ji , Wada Makoto 
Published: July 2006

Abstract
RCu·BF3 reacted with 1-ethoxycarbonylpyridinium chloride at the 4-position with almost complete regio-selectivity (&gt;99%) to afford the corresponding 1,4-dihydropyridine derivatives in high yields (81–94%). The dihydropyridines were oxidized by oxygen to give 4-alkyl(aryl)pyridines (38–68%). Grignard reagents also reacted with 1-t-butyldimethylsilylpyridinium triflate with almost complete regioselectivity (&gt;99%) to afford the corresponding 1,4-dihydropyridines, which were easily oxidized by oxygen to give 4-substituted pyridines in higher yields than above (58–70%).
Effects of Pore Size Distribution on the Catalytic Performance for Coal Liquefaction. I. The Activity and Selectivity of the Catalyst
Authors: Shimada Hiromichi , Kurita Minoru , Sato Toshio , Yoshimura Yuji , Kawakami Tomohiro , Yoshitomi Suehiko , Nishijima Akio 
Published: July 2006

Abstract
Coal liquefaction experiments were carried out by using seven catalysts with different pore structures. As for the unimodal catalysts, the total conversion increased with the pore radius of the catalyst because of the lesser pore-diffusional limitation. However, the ratio of oil to oil-plus-asphaltene decreased with the pore radius. In the case of a large-pore catalyst, heavy components with a large molecular size and a low reactivity can approach the intra-particle active sites and occupy them to prevent the hydrocracking of asphaltene to oil. Bimodal catalysts with micropores (r&lt;10 nm) and macropores (r&gt;300 nm) gave higher values of both the coal liquefaction and the oil yields than did the unimodal catalysts. The presence of macropores seems to enhance the pore diffusion and increase the efficiency of the micropore use, while mesopores with radii between 10 nm and 300 nm did not make such a high contribution to the pore diffusion as was shown for the macropores. For the removal of heteroatoms, there was little difference in the performance among the catalysts with different pore structures. It is suggested that the active sites for the heteroatom removal are deactivated easily by the heavy components.

Authors: Kikuchi Osamu 
Published: July 2006

Abstract
The 1,2-hydrogen migration from the 90°-twisted propene to the corresponding carbenes was examined on the basis of ab initio MO CI calculations. It was predicted that, in the polarized zwitterionic states of the twisted propene, the 1,2-hydrogen migration occurs from the negatively-charged carbon atom to the positively-charged one.

Authors: Wada Takahiro , Yokotani Fumiko , Matsuo Yoshihiro 
Published: July 2006

Abstract
Ternary system CH3CO2Na–Na2HPO4–H2O was investigated between 38 and 75 °C. No double salt formation occurs in this temperature range. Saturated CH3CO2Na solution has a strong dehydrating influence on Na2HPO4·2H2O and Na2HPO4·7H2O. The lowest formation temperature for anhydrous Na2HPO4 is about 57 °C.
Adsorption Isotherm Equation for Coexistence of Two Kinds of Metal Ions in Acidic Solution on Chelating Resin
Authors: Urano Kohei , Fujii Nobuhiko 
Published: July 2006

Abstract
Adsorption isotherms for the coexistence of two metal ions (combinations of Zn2+, Cd2+, and Pb2+) in acidic solutions on chelating resins were measured at 25 °C. They were analyzed in relation to the adsorption isotherm equation of a single metal ion, Q=Qmax⁄(1+ACM−αCHβ), as was reported in the preceding paper. It is found that the adsorption isotherms of two metal ions (i and j) in acidic solution on chelating resins can be generally expressed by the equation;
Q i,j=Qmax⁄{1+AiCi−αiCHβi(1+Ki,jCjαjCH−βj)}
over wide ranges of concentrations of the metal ion, C, and the hydrogen ion, CH (mol dm−3). Where Qi and Qi,j are the adsorption amounts (m mol/g-dry resin) of i metal ion in the absence and in the coexistence of j metal ion. Qmax is the maximum adsorption amount, α and β are parameters in the adsorption of single metal solution, A and K are correction factors, and subscripts i and j identifing i and j metal ions. The adsorption capacities of two metal ions in acidic solution can be obtained from the isotherms parameters Ai, αi, αj, βi and βj for an individual single metal ion and only one additional parameter Ki,j is needed.
The Volume, Adiabatic Compressibility, and Viscosity of Amino Acids in Aqueous Alkali-chloride Solutions
Authors: Ogawa Toshio , Mizutani Kiyoshi , Yasuda Motoo 
Published: July 2006

Abstract
The apparent molal volumes (φV), apparent molal adiabatic compressibilities (φKS), and relative viscosities (nr) at 25 °C have been obtained for the following amino acids in aqueous alkali-chloride solutions from measurements of the density, the ultrasonic velocity, and the flow time: glycine, l-alanine, β-alanine, α-aminoisobutyric acid, l-serine, and l-threonine. Viscosity measurements were also carried out in water for reference. The alkali chlorides used were lithium, sodium, and potassium chlorides. The limiting values φVo, φKSo and the extended Jones-Dole viscosity coefficients, B and D, were calculated by a linear extrapolation using the least-squares method. All the φVo, φKSo, and B values obtained in the mixed solvents were larger than the corresponding ones in water, except in a few cases of the B coefficient. The results are discussed in terms of the dehydration effect of the electrolytes upon the amino acids.
The Three-dimensional Structure of Plasminostreptin, a Bacterial Protein Protease Inhibitor, at 2.8Å Resolution
Authors: Kamiya Nobuo , Matsushima Masaaki , Sugino Hiromu 
Published: July 2006

Abstract
The three-dimensional structure of plasminostreptin, a bacterial protein protease inhibitor from Streptomyces antifibrinolyticus, was determined at 2.8Å resolution by the multiple isomorphous replacement technique. A dimer with the molecular weight of 11,402×2 was included in an asymmetric unit of the crystal. The monomer, composed of 109 amino acid residues, consisted of an antiparallel twisted β-sheet with five strands, two short helices, and irregular polypeptide-chain segments. The reactive site of plasminostreptin belonged to one of these irregular polypeptide-chain segments. The two monomers in the dimer were related by a non-crystallographic pseudo-two-fold axis, and the two β-sheets were arranged face-to-face with each other. The averaged angle between the strands of the two β-sheets was approximately 30° clockwise. In spite of 37 amino acid substitutions including the reactive site residues, the tertiary and quaternary structures of plasminostreptin were similar to those of Streptomyces subtilisin inhibitor (SSI). The main-chain conformations of the reactive site of plasminostreptin were similar to those of SSI and other protease inhibitors analysed previously. Moreover, the conformations of the side chain of the evolutionary conservative asparagine in the so-called “secondary contact region” resembled those found in the inhibitors of the pancreatic secretory trypsin inhibitor family.

Abstract
To synthesize internal alkenyldialkylboranes, coupling reactions were carried out by using 1-halo-l-alkenyldialkylboranes and Grignard reagents. Hydrogen peroxide oxidation and protonolysis with acetic acid of the reaction product revealed that internal (E)-alkenyldialkylborane was formed in 60–90% yield.
Hydrophobic Vitamin B12. III. Incorporation of Hydrophobic Vitamin B12 Derivatives into Single-Compartment Vesicles and Their Alkylation in Various Molecular Aggregates
Authors: Murakami Yukito , Hisaeda Yoshio , Ohno Teruhisa 
Published: July 2006

Abstract
The incorporation of hydrophobic vitamin B12 derivatives into the single-compartment vesicles of N,N-didodecyl-Nα-[6-(tyimethylammonio)hexanoyl]-l-alaninamide bromide (N+C5Ala2C12) was found to be primarily concerned with the extent of insolubility of the cobalt complexes in the aqueous bulk phase, while such incorporation into the single-walled vesicles of N,N-ditetradecyl-Nα-[6-(trimethylammonio)hexanoyl]-l-histidinamide bromide (N+C5His2C14) was enhanced by the coordination interaction between the cobalt complex and the imidazolyl group of the lipid. In molecular aggregates formed with hexadecyltrimethylammonium bromide, α-[4-(1,1,3,3-tetramethylbutyl)phenyl]-ω-hydroxypoly(oxyethylene), or N+C5Ala2C12, the alkylation rates of a hydrophobic vitamin B12 with 1-bromo-2-methylpropane and methyl 2-methyl-3-bromopropanoate were much enhanced relative to those in methanol. In the N+C5Ala2C12 vesicle, a two-step mechanism was observed for the alkylation with the latter reagent. The possible origin of such rate enhancement was discussed.

Published: July 2006

Abstract
1:1 Copper(II) complexes with N,N′-bis(2-hydroxyethyl)malonamide (abbreviated as H4maae), MCu(maae) (M=Ca, Sr, Ba), and 2:1 copper(II) complexes with N,N′-bis(5-amino-3-hydroxypentyl)malonamide and N,N′-bis(5-amino-3-hydroxypentyl)oxamide (abbreviated as H4madpl and H4oxdpl, respectively),[Cu2(madpl)]·3H2O and [Cu2(oxdpl)]·2H2O, were prepared and characterized by elemental analyses, infrared and electronic spectra, and magnetic susceptibilities. The 2:1 complexes exhibit a band at 23.3–27.0×103 cm−1 characteristic of alkoxo-oxygen bridged structure and show a very strong antiferromagnetic interaction, whereas the 1:1 complexes show no such band and their magnetic moments fall in the range of those for ordinary mononuclear copper(II) complexes. The crystal structures of [Cu2(madpl)]·3H2O and BaCu(maae)·7H2O were determined by the single-crystal X-ray diffraction method. The structure of [Cu2(madpl)]·3H2O consists of alkoxo-oxygen bridged binuclear molecules, where madpl4− functions as a sexadentate binucleating ligand with an N2O2N2 donor set. In BaCu(maae)·7H2O, the basic unit is a hetero-metal tetranuclear entity (H2O)2{Ba(H2O)4Cu-(maae)}2 in which the two Ba2+ are linked sharing two H2O and are also bound to alkoxo oxygens of Cu(maae)2−. On the basis of the crystal structures, their spectral properties were discussed.
Enantioselectivity Enhancement in the Deacylation of N-Acyl Amino Acid Esters by Vesicular Systems of Long Chain Dipeptide Nucleophiles and a Cationic Double Chain Surfactant

Published: July 2006

Abstract
The enantioselective deacylation of short chain and long chain N-acyl amino acid p-nitrophenyl esters, CH3(CH2)nCONH\overset*CH(R)–CO2C6H4NO2-p (R=C6H5CH2, (CH3)2CHCH2, CH3; n=0, 8, 12), was carried out at 4–25°C (pH 7.68) with the vesicular systems composed of N,N-didodecyl-N,Ndimethylammonium bromide and long chain nucleophiles, Nα-dodecanoyl-l-histidine, Nα-(N-dodecanoyl-l-leucyl)-l-histidine(3a), Nα-(N-dodecanoyl-l-phenylalanyl)-l-histidine (3b), and N-(Nα-dodecanoyl-l-histidyl)-l-leucine (3c). Both the deacylation rate and the enantioselectivity were the largest in the deacylation of the substrates possessing a long N-acyl chain (n=8) with the efficient dipeptide nucleophiles (3a and 3b) including the l-histidine moiety in their terminal position, and the neighboring amino acid binding to the l-histidine in 3a, 3b, and/or 3c was found to play an important role in the enhancement of enantioselectivity. The lowering of the reaction temperature decreased the deacylation rate and increased the enantioselectivity. The maximum enantiomer rate ratio of 24.5 was obtained in the deacylation of p-nitrophenyl N-dodecanoylphenylalaninates with the dipeptide nucleophile 3b. The characteristic features of the present reaction are discussed on the basis of kinetic parameters (binding constants and activation parameters) and isokinetic relationships.
Reactions of 2-Chloroacyltrimethylsilanes with Grignard Reagents. Preparation of 3-(Trimethylsilyl)-2-alkanones and 2-(Trimethylsilyl)-1-alkanols
Authors: Sato Toshio , Matsumoto Kazuhisa , Abe Toru , Kuwajima Isao 
Published: July 2006

Abstract
Reactions of 2-chloroacyltrimethylsilanes with Grignard reagents have been examined. Thus, treatment with methylmagnesium iodide affords the corresponding 3-(trimethylsilyl)-2-alkanones through an initial addition followed by removal of chloride anion and 1,2-rearrangement of silyl group. In contrast, the reaction proceeds with 2 equiv of the Grignard reagents bearing β-hydrogen to give 2-(trimethylsilyl)-1-alkanols, where initial reduction of the silylcarbonyl group followed by such rearrangement and addition of the Grignard reagents to the resulting 2-(trimethylsilyl)alkanals have been proposed.
Axially Dissymmetric Bis(aminophosphine)s Derived from 2,2′-Diamino-1,1′-binaphthyl. Synthesis and Application to Rhodium(I)-Catalyzed Asymmetric Hydrogenations
Authors: Miyano Sotaro , Nawa Masayoshi , Mori Akira , Hashimoto Harukichi 
Published: July 2006

Abstract
Axially dissymmetric bisphosphine ligands, (R)- and (S)-2,2′-bis(diphenylphosphinoamino)-1,1′-binaphthyl (BDPAB) and (R)-2,2′-bis[N-(diphenylphosphino)methylamino]-1,1′-binaphthyl (Me-BDPAB) were conveniently prepared from 2,2′-diamino-1,1′-binaphthyl. The rhodium(I)-catalyzed asymmetric hydrogenation of α-acylamidoacrylic acids and esters gave the corresponding amino acids of up to 95% optical purity. The sign of the centro-chirality of the product amino acids was always the same to that of the axial chirality of the ligand in both cases of BDPAB and Me-BDPAB.

Abstract
Electrochemical crystallizations of the complexes of naphthaceno[5,6-cd: 11,12-c′d′]bis[1,2]dithiole (TTT), anthra[1,9-cd:4,10-c′d′]bis[1,2]dithiole (TTA), anthra[1,9-cd:4,10-c′d′]bis[1,2]diselenole (TSA), and naphtho[1,8-cd:4,5-c′d′]bis[1,2]dithiole (TTN) were made in 1,1,2-trichloroethane or tetrahydrofuran as a solvent. Most of the crystals were obtained with non-stoichiometric compositions, and they included the solvent. Some charge-transfer complexes including the above donors were also made by a diffusion method. The electrical conductivities of the crystals were measured by a two-probe or four-probe method. TTT(PF6)0.61 was found to be the most conductive materials in the complexes studied. Its electrical conductivity was 762 (Ω cm)−1 at room temperature, and it showed metallic behavior above 220 K. The conductivities of the other complexes varied widely in the range 102–10−7 (Ω cm)−1.
Restricted Rotation Involving the Tetrahedral Carbon. LV. Differential Effects of the peri-Substituents on the Rotational Barriers in 9-Ethyl-, 9-Allyl-, and 9-Benzyltriptycenes
Authors: Yamamoto Gaku , Oki Michinori 
Published: July 2006

Abstract
Energy barriers to rotation about the bridgehead-to-substituent bond in 9-ethyl-, 9-allyl-, and 9-benzyltriptycene derivatives with varying degrees of peri-substitution were studied by dynamic NMR and in one case by the classical kinetic method. In the singly peri-substituted series (1,4-dimethoxy derivatives) the barrier decreases in the order of 9-ethyl&gt;9-allyl&gt;9-benzyl. In the doubly peri-substituted series (1,8-dichloro derivatives) the barriers are alike irrespective of the 9-substituent, and in the triply peri-substituted series (1,4-dimethyl-8,13-dichloro derivatives) the barrier decreases in the order of 9-benzyl&gt;9-allyl&gt;9-ethyl. The reversal of the trend on the change in peri-substitution patterns may be explained on the basis of the change in the interaction between the peri- and 9-substituents in both the ground and the transition states.
Basic Behaviors and Properties of the Electrodeposited Polyaniline
Authors: Kitani Akira , Izumi Jinko , Yano Jun , Hiromoto Yasuyuki , Sasaki Kazuo 
Published: July 2006

Abstract
Basic behaviors and properties of polyaniline(PA) deposited anodically on platinum electrodes have been studied on the following points. 1) Effect of the mode of electrolysis and supporting electrolytes in the film forming process. 2) Characteristics of charging-discharging processes. 3) Electric conductivity and elemental composition of PA. The different modes of electrolysis do not affect the characteristics of the PA electrode obtained. The growth rate of PA film is 2.7–2.8 times faster in sulfuric acid than in perchloric, nitric or hydrochloric acid. It is indicated that there are two types of doping; one is associated with the acid-base equilibrium between amino or imino group in the film and proton in the solution and the other is associated with the excess charge in the film produced by anodic oxidation. The electric conductivity of PA markedly decreases by the immersion in alkali solutions. The release of doped anion from PA by treating with an alkali solution is confirmed by the elemental analysis. The amount of anions occluded by the electrochemical doping process is determined to be 0.25–0.29 per monomer unit.
Intramolecular Interactions in the Ground and Excited States of 1,3-Bichromophoric Propanes in the Aqueous Cyclodextrin Solutions
Authors: Itoh Michiya , Fujiwara Yoshihisa 
Published: July 2006

Abstract
The enhanced fluorescence of several 1,3-bichromophoric propanes in aqueous cyclodextrin solutions has been investigated by the steady-state fluorescence spectra and fluorescence lifetimes. 1-(9,10-Dicyano-2-anthryl)-3-(1- and 2-naphthyl)propanes exhibit the intramolecular charge transfer complex fluorescence generated in the ground state in the presence of γ-cyclodextrin. Two bichromophoric propanes, 1,3-di-2-naphthylpropane and 1-(1-naphthyl)-3-(2-naphthyl)propane, in the aqueous β- and γ-cyclodextrin solutions show not only the intramolecular excimer but also the ground state complex fluorescences, though the ground state complex formation of dinaphthylpropane has never been observed in the homogeneous solution even at low temperature. The intramolecular interactions in the ground and excited states seem to be attributable to their intramolecularly geometrical restriction in the extraordinary nonpolar cavity of the cyclodextrins.
