Syntheses and Characterization of Bromo- and Chloro(phthalocyaninato)bismuth(III) Complexes
Authors: Isago Hiroaki , Kagaya Yutaka 
Published: July 2006

Abstract
By the reactions of BiX3 (X = Cl−, Br−, I−, and NO3−) with Li2(pc) (pc = phthalocyaninate dianion, C32H16N82−) in dimethyl sulfoxide, N,N-dimethylformamide, acetonitrile, and acetone, [Bi(pc)X] complexes have been produced. These complexes were also produced by heating a mixture of BiX3 and phthalonitrile. Among them, [Bi(pc)Cl] and [Bi(pc)Br] were isolated for the first time as a phthalocyanine complex of group-15 elements and successfully characterized by elemental analyses, solution chemistry, electronic and IR spectroscopy. The latter two complexes were soluble in polar solvents, but were insoluble in nonpolar solvents. In solutions, bismuth(III) in [Bi(pc)X] was labile and was readily expelled from a pc ring by a trace amount of water, acids, and bases, and it was replaced by a divalent transition metal upon the addition of MSO4 (M = cobalt(II), nickel(II), copper(II), and zinc(II)) forming [M(pc)]. The electronic and IR spectra of the [Bi(pc)X]s were characteristic of the usual metallophthalocyanines, except that a hyper metal-to-ligand charge-transfer band appeared in their electronic spectra.
Intercalation of Ferrocene and Its Derivatives into VxNb1−xOPO4 (x = 0, 0.06, 0.11, and 0.21) Interlayer Spaces
Authors: Okuno Shoji , Matsubayashi Gen-etsu 
Published: July 2006

Abstract
Ferrocene, FcH [Fc = (C5H5)Fe(C5H4)], (ferrocenylalkyl)trimethylammonium iodides, [Fc(CH2)nNMe3]+I− (n = 1 or 2), and 1,2-diferrocenylethane, FcCH2CH2Fc, have been intercalated into the V0.21Nb0.79OPO4 interlayer space. The V(V) ion is reduced by the iodide ion and/or the Fc centers, the Nb(V) ion being not reduced. The long-axis direction of the guest molecules is arranged approximately parallel to the swelling V0.21Nb0.79OPO4 sheet. Some Fc centers of FcCH2CH2Fc and FcCH2CH2NMe3+ are not oxidized in spite of their proximity to the metal ion site of the V0.21Nb0.79OPO4 lattice because most of the V sites are isolated from other V sites owing to the low V contents. Ferrocenylalkylamines, FcCH2NMe2 and FcCH2CH2NH2, have been intercalated into the VxNb1−xOPO4 (x = 0, 0.06, 0.11, and 0.21) interlayer spaces, accompanied with the protonated amino groups and the Nb(V) and reduced V(IV) sites. ESR signals of the V0.06Nb0.94OPO4 intercalation compounds exhibit hyperfine structures due to the V(IV) nucleus (I = 7/2). With the increase of the V content in the host lattice, ESR signals are further broadened owing to the dipole–dipole and/or exchange interactions among the V(IV) sites.

Published: July 2006

Abstract
Four geometrical isomers of [Co(gly)(en)Co(edda)(μ-OH)2]+ were prepared by treating a solution containing [Co(edda)(OH2)2]+ and [Co(gly)(en)(OH2)2] 2+ under basic condition and optically resolved by the chromatographic method. The geometrical structures and absolute configurations of the optically active isomers were assigned on the basis of the NMR, UV, and CD spectral data; the assignments were confirmed based on the spectral data of the mononuclear species which were obtained by the acid hydrolysis of each isomer. Two of the four geometrical isomers are constructed with the α-[Co(edda)(μ-OH)2] and mer(O)-[Co(gly)(en)(μ-OH)2] moieties, and the other two with the β-[Co(edda)(μ-OH)2] and fac(O)-[Co(gly)(en)(μ-OH)2] moieties, the dinuclear structures being stabilized by the two N–H···O hydrogen bonds between the amino H on one metal ion and the carboxyl O on the other metal ion in the dinuclear complex ion.
Preparation and Some Properties of Tetraamine Cobalt(III) Complexes with Monodentate Thiolate or Sulfinate Ligands
Authors: Konno Takumi , Umehara Hideki , Okanoto Ken-ichi , Hidaka Jinsai 
Published: July 2006

Abstract
Tetraamine cobalt(III) complexes with monodentate thiolate ligands, [Co(RS)2(amine)4]+, were newly prepared, where R is CH3 or C2H5 and (amine)4 is bis(ethylenediamine) ((en)2), triethylenetetramine (trien), or tris(2-aminoethylamine) (tren). The (en)2 and trien thiolato complexes selectively formed the cis and cis–α isomers, respectively. The oxidation reactions of [Co(RS)2{(en)2 or (trien)}]+ with use of excess H2O2 gave the corresponding S-bonded sulfinato complexes [Co(RSO2-S)2{(en)2 or (trien)}]+ with retention of the initial geometries, while [Co(CH3SO2-S)2(tren)]+ was not formed by the same oxidation reaction of [Co(CH3S)2(tren)]+. The cis-(en)2 and cis–α-trien complexes were optically resolved by the fractional crystallization or column chromatography. The obtained isomers were characterized on the basis of the absorption, CD, and 13C NMR spectra. The thiolato complexes exhibited absorption spectral changes with time in aqueous solutions, which are ascribed to the replacement of the thiolate ligands by H2O.

Abstract
Cationic rearrangement of 1,4-bis(diarylhydroxymethyl)pentacyclo[4.2.0.02,5.03,8.04,7]octanes (1) in formic acid gave new cage compounds, 8,8-diaryl-2-diarylmethylene-exo-5-(formyloxy)tetracyclo[4.3.0.03,9.04,7]nonan-7-ols (3) and new cage-degradation products, 5,5-diaryl-4-[4-(diarylmethylene)-2-cyclobutenyl]-2-cyclopenten-1-ones (4) along with Wagner–Meerwein rearrangement products, pentacyclo[5.3.0.02,5.03,9.04,8]decanes (5; C2-bishomocubanes) and pentacyclo[5.3.0.02,6.03,9.04,8]decanes (6; D2h-bishomocubanes). 9,9-Diaryl-4-(diarylhydroxymethyl)pentacyclo[4.3.0.02,5.03,8.04,7]nonan-1-ols (2) gave 4, 5, and 6 without the formation of 3. A Wagner–Meerwein 1,2-bond shift of 1 gave key intermediates 2 which were converted into 3 via homoallylic rearrangement, into 4 via pinacol–pinacolone-like rearrangement, or into 5 and 6 via Wagner–Meerwein rearrangement.
Solvent Effects on Extraction of Sodium Picrate with 15-Crown-5. The Determination of Ion-Pair Formation Constant of Crown Ether–Metal Salt 1 : 1 : 1 Complex in Water
Authors: Takeda Yasuyuki , Takagi Chihiro 
Published: July 2006

Abstract
In order to determine the ion-pair formation constant of a crown ether–metal salt complex (1 : 1 : 1) in water, an equation is derived from the regular solution theory. Then, the theoretical predictions are verified experimentally by solvent extraction with 15-crown-5 (15C5), sodium picrate (NaA), and various organic solvents of low dielectric constant. The partition constants of 15C5 and the actual overall extraction constants of NaA with 15C5 were determined at 25 ± 0.2 °C. The partition constants of the Na(15C5)A complex are calculated from these data, the literature value for the complex-formation constant of Na(15C5)+ in water, and the ion-pair formation constant (KNa(15C5)A) in water determined in this study (log KNa(15C5)A = 4.09 ± 0.23 at 25 °C). The distribution behavior of 15C5 and Na(15C5)A is explained by the regular solution theory. The obtained molar volumes V/cm3 mol−1 and solubility parameters δ/cal1/2 cm−3/2 are as follows; V15C5 = 189 ± 34, VNa(15C5)A = 215 ± 46, δ15C5 = 12.0 ± 0.1, and δNa(15C5)A = 12.0 ± 0.1.

Abstract
The anodic oxidation of polyaniline in aqueous solutions containing SO42− and PO43− ions caused an exothermic change at lower potential and an endothermic change at higher potential, but only the exothermic change was observed in the anodic process of polyaniline in a solution containing ClO4− ions.

Effect of Some Tetrabutylammonium Salts on the Impedance Behavior of Indium in Acidic Media
Authors: El-Sayed Adbel -Rahman , Mohran Hossnia , Rashwan Farouk 
Published: July 2006

Abstract
The ac impedance of a planar indium electrode in both HCl and H2SO4 solution was measured at −20, 0.0, and 10 mV vs. the open circuit potentials. Various amounts of Bu4NBF4, Bu4NPF6, and Bu4NClO4 were gradually introduced to the electrolytic solution and the impedance of the electrode was remeasured. Subsequently, Rs, Rp, and Cdl, in the absence and presence of the additives, were computed and compared. It was found that Bu4NBF4 has an inhibitive action in both acids. On the other hand, acceleration of the electrochemical processes in the presence of Bu4NPF6 also in both acids, is observed. However, some retardation of the electrode reactions was obtained at the lowest concentration of the additive only in HCl. It is noteworthy that Bu4NClO4 has contradictory effects on the electrochemical processes, i. e. an inhibitive action in HCl solution, whereas in H2SO4 the electrode reactions are significantly enhanced.
Solvent Dependence of Magnetic Field Effects upon Photoisomerization of 2-(3,3-Dimethyl-1-butenyl)naphthalene in the Presence of Electron Acceptors
Authors: Sakuragi Hirochika , Nakagaki Ryoichi , Naitoh Kazuhiko , Oguchi Takahisa , Arai Tatsuo , Tokumaru Katsumi , Nagakura Saburo 
Published: July 2006

Abstract
The efficiency of isomerization of trans-2-(3,3-dimethyl-1-butenyl)naphthalene (t-BN) in the presence of electron acceptors was reduced by an applied magnetic field in polar solvents such as acetonitrile. This effect together with laser flash photolysis studies indicates that the precursor of isomerization is the BN triplet arising from intersystem crossing of a singlet radical pair consisting of a t-BN cation and an acceptor anion. The external magnetic field effect as well as laser flash photolysis was employed to estimate the contribution of ion radical pairs to the isomerization of t-BN in the presence of p-dicyanobenzene in various solvents. The t-BN triplet was produced most efficiently almost through an exciplex in chloroform (ε = 4.8) among the employed solvents.
A Convenient Synthetic Method for Pure Oxo(phthalocyaninato)titanium(IV) and Application to Other Metal Phthalocyanines
Authors: Yao Jiachang , Yonehara Hisatomo , Pac Chyongjin 
Published: July 2006

Abstract
High-yield synthesis of pure oxo(phthalocyaninato)titanium(IV) was conveniently achieved by heating a mixture of 1,2-dicyanobenzene, titanium(IV) butoxide, urea, and 1-octanol at 150 °C. It is suggested that a key pathway of the efficient condensation reaction is the complex formation of titanium(IV) butoxide with ammonia generated by the nucleophilic attack of 1-octanol to urea. Applicabilities of this method were investigated for condensation reactions of 1,2-dicyanobenzene with other metal alkoxides.

Authors: Kunugi Shigeru , Hayashi Yuuji , Koyasu Akira , Tanaka Naoki , Shiraishi Makoto 
Published: July 2006

Abstract
In order to understand the effect of the structures of the surrounding medium on biocatalytic reactions, hydrolytic catalysis by subtilisin Carlsberg in a ternary system containing octyl β-D-glucopyranoside (β-OG), water, and octanol (OcOH) was studied, with special reference to the enzyme reactivity and the morphology of the surfactant aggregates.
First, the effect of β-OG and other alkyl D-glucopyranosides (AG) on the subtilisin reaction was studied in the surfactant/water binary system; all four surfactants tested were found to inhibit the subtilisin catalysis.
Then, a detailed phase diagram of β-OG/water/octanol was determined and several liquid crystalline phases were found.
When the subtilisin reactions were measured in several compositions in the phase diagram, the maximum of the apparent rate was observed in reversed micells as well as in the reversed hexagonal phase at a certain [water]/[surfactant] ratio (wo). The apparent optimal wo was calculated to be around 5—6. These results were compared with the results in another ternary system of Aerosol OT/water/isooctane.
Deuterated Derivatives of 3,5-Dimethyl-1-(4-nitrophenyl)pyrazole for Nonlinear Optical Materials
Authors: Okazaki Masaki , Uchino Nobuhiko , Nozaki Nobuharu , Kubo Kazumi 
Published: July 2006

Abstract
A weak absorption of laser light by a nonlinear optical crystal causes a noticeable temperature rise in the crystal. Such absorption may undesirably shift the reflactive indices (some optical characteristics) of the crystal. 3,5-dimethyl-1-(4-nitrophenyl)pyrazole [DMNP], an excellent nonlinear optical material, was deuterated in order to suppress its absorption in the 1 μm wavelength region.
Three deuterated deriatives were synthesized; their crystal structures were identical with that of DMNP. The deuteration of the pyrazole part including the two methyl moieties proved to be more effective than deuteration of the phenyl part (benzene ring) with regard to a reduction of the IR absorption.
A good correlation was confirmed between the temperature elevation under laser irradiation and IR absorption.

Authors: Miura Yozo , Oka Hiroyuki , Yamano Eiji , Teki Yoshio , Takui Takeji , Itoh Koichi 
Published: July 2006

Abstract
The oxidation of N-[(4-nitrophenyl)thio]-2-t-butyl-1-aminopyrene yielded a quite persistent and oxygen-insensitive N-[(4-nitrophenyl)thio]-2-t-butyl-1-pyrenylaminy radical (3), which was isolated as reddish-black fine needles. The hyperfine coupling (hfc) constants for the aminyl were determined by ESR and 1H ENDOR measurements, indicating that there is an extensive delocalization of the unpaired electron from the nitrogen onto the pyrene ring. A comparison of the hfc constants with structurally close N-[(4-nitrophenyl)thio]-7-t-butyl-1-pyrenylaminyl (1) and N-[(4-nitrophenyl)thio]-2,7-di-t-butyl-1-pyrenylaminyl (2) showed that although the spin-density distribution of 3 is similar to that of 2, it is greatly different from that of 1. Magnetic susceptibility measurements of 3 in solid radical crystals showed that the magnetic interaction between the radical spins is strongly antiferromagnetic, giving J/k = −108 and −192 K for 2 and 3, respectively.
Preparation of Some Multifunctionalized Methylenephosphines by Reactions of Chloro[(2,4,6-tri-t-butylphenyl)phosphinidene]methyllithiums with Carbonyl Compounds
Authors: Yoshifuji Masaaki , Ito Shigekazu , Toyota Kozo , Yasunami Masafumi 
Published: July 2006

Abstract
Either a (Z)- or (E)-chloro(phosphinidene)methyllithium reagent, prepared from dichloromethylene- or (E)-chloromethylene-phosphine with butyllithium, respectively, reacted with carbonyl compounds to give the corresponding functionalized methylenephosphines. Although the stereochemistry of the products was retained during the initial step of the reaction, in some cases E/Z isomerization reactions occurred to the resulting methylenephosphines. Imidazolidinediones bearing the P=C bond were obtained for the first time by a reaction of the E-lithium reagent with phenyl isocyanate; the structure of the Z-isomer was determined by X-ray analysis.

Kinetics and Mechanism of the High-Temperature Selenidization of Titanium
Authors: Naruke Haruo , Yamada Kenji , Kakegawa Kazuyuki , Sasaki Yoshinori 
Published: July 2006

Abstract
A titanium sheet was selenidized in selenium vapor of 1.33—13.33 kPa at 823—973 K by means of a sealed-tube method. X-Ray diffraction patterns and an electron-probe microanalysis of the product films showed the layer to comprise only TiSe2. Since the selenidization obeyed a parabolic rate law under all of the conditions employed, the rate-determining step was a diffusion process. The parabolic rate constant (Kp) could be expressed as a function of the absolute temperature, and was approximately proportional to the partial pressure of Se2. A marker experiment indicated that selenium was the component which diffused in the product film.
Kinetics and Mechanisms of Photoinduced Reduction of Methylviologen by N-Alkyltetraphenylporphyrinatozinc(II) in Methanol
Authors: Tsukahara Keiichi , Sawai Naoko , Hamada Satoko , Nakazawa Takashi , Nakagaki Ryoichi 
Published: July 2006

Abstract
N-3-Bromopropyl-5,10,15,20-tetraphenylporphyrinato(1-)chlorozinc(II), [Zn(BrPrtpp)Cl], catalyzed the formation of a methylviologen radical cation (MV+•) on steady-state irradiation of degassed methanol solutions with visible light (&gt;420 nm) in the presence of triethanolamine (TEOA). The initial rate (Vi) of the formation of MV+• was of first order in the concentration of MV2+ and in the intensity of light and was independent of the concentration of TEOA above 0.025 M. Plots of Vi vs. the concentrations of [Zn(BrPrtpp)Cl] were curved. The fluorescence of [Zn(BrPrtpp)Cl]*, whose lifetimes are τ1s = 0.7 ns (48%) and τ2s = 2.0ns (52%) in methanol at 25 °C, was not quenched by MV2+. The excited triplet state of [Zn(BrPrtpp)Cl] (τ0t = 3.2 μs in MeOH) was efficiently quenched by MV2+ (kq = (6.0 ± 0.6) × 107 M−1 s−1 at 25 °C, 1 M = 1 mol dm−3). The thermal back electron-transfer reaction between [Zn(BrPrtpp)Cl]+• and MV+• was also observed (kb = (1.2 ± 0.2) × 1010 M−1 s−1). On the basis of the steady-state irradiation kinetics and ns-laser flash photolysis, the quantum yield of the excited triplet state of [Zn(BrPrtpp)Cl] can be evaluated to be 0.98 ± 0.02. [Zn(BrPrtpp)Cl] was found to be a more effective photocatalyst than [Zn(Prtpp)Cl] (HPrtpp = N-propyl-5,10,15,20-tetraphenylporphyrin) or [Zn(tpp)] (H2tpp = 5,10,15,20-tetraphenylporphyrin) under the present experimental conditions.

Abstract
Trifluoroacetaldehyde azine (TFAcAz) was prepared and its reactivity was investigated. TFAcAz is readily attacked by nucleophiles such as trialkylamines, methanol, and water.

A cyclic dimer containing a 1,4-dihydro-1,2,4,5-tetrazine ring was obtained by the reactions of TFAcAz with trialkylamines. 1,2-Adducts were found to be produced by the reactions of TFAcAz with methanol and with water.
Formalized Drawing of Fullerene Nets. 1. Algorithm and Exhaustive Generation of Isomeric Structures
Authors: Yoshida Mitsuho , Osawa Eiji 
Published: July 2006

Abstract
A simple formalism for unfolding the fullerene structure onto a planar lattice is proposed. We recommend using deltahedra containing twelve penta-coordinated vertices as the geometrical precursors of fullerenes, and unfolding them onto a planar lattice according to Dürer’s style. This old style has several unique features that allow a priori drawing of diagrams that fold to fullerenes. Combined with the known algorithm for generating approximate atomic coordinates from the connectivity, which can be readily read off from the net diagram, the present method provides an alternative way of exhaustive generation of isomeric fullerene structures.
Asymmetric Synthesis of a β-Lactam Framework via the Conjugate Addition of Amidocuprates(I) to Chiral Enoates
Authors: Asao Naoki , Uyehara Tadao , Tsukada Naofumi , Yamamoto Yoshinori 
Published: July 2006

Abstract
Amidocuprate(I) reagents {Li[Cu(NR2)2]} and higher order cyanocuprates(I) {Li2[Cu(CN)(NR2)2]} have been developed as a new class of nitrogen nucleophiles. These reagents underwent regioselective 1,4-additions to α,β : γ,δ-dienoates, whereas NHR2 gave a 1,6-addition product and the lithium reagent LiNR2 afforded a mixture of 1,4- and 1,2-addition products. The amidocuprates(I) were added to chiral α,β : γ,δ-dienones having a 8-phenyl-p-menth-3-yl or a 10,2-bornanesultam chiral auxiliary in order to produce 1,4-adducts in good to high diastereoselectivity. The addition of Li[Cu{N(Bn)(TMS)}2] and Li2[Cu(CN){N(Bn)(TMS)}2] to 8-phenyl-p-menth-3-yl 5-phenyl-2,4-pentadienoate or N-(5-phenyl-2,4-pentadienoyl)-10,2-bornanesultam produced an (R)-chirality at the β-position. The 1,4-addition of Li2[Cu(CN){N(Bn)(TMS)}2] to the bornanesultam, followed by trapping with acetaldehyde, gave the α-(1-hydroxyethyl)-β-amino derivative as a single isomer in good yield. This three-component coupling was used in an asymmetric synthesis of a β-lactam.
