The Electrodepositions of Copper and Nickel from Their Trifluoroacetate–N,N-Dimethylformamide Baths
Authors: Takei Tatsuko 
Published: July 2006

Abstract
This paper will deal with the electrodepositions of copper and nickel from Cu(CF3COO)2–HCON(CH3)2, Cu(CF3COO)2–HCON(CH3)2–citric acid, Ni(CF3COO)2–HCON(CH3)2, and Ni(CF3COO)2–HCON(CH3)2–additives baths. The properties of these baths and the mechanism of the electrodeposition of copper from the Cu(CF3COO)2–HCON(CH3)2–citric acid bath were studied. The solubility of Cu(CF3COO)2 in 100 g of HCON-(CH3)2 was 180 g at 20 °C. The specific conductances of the Cu(CF3COO)2–HCON(CH3)2 and Ni(CF3COO)2–HCON(CH3)2 baths were lower than those of the Cu(CF3COO)2–HCONH2 and Ni(CF3COO)2–HCONH2 baths. Cu2O was electrodeposited at the cathode, while copper was not easily obtained from the Cu(CF3COO)2–HCON(CH3)2 bath. By dissolving citric acid in the bath, copper electrodeposition was made easier. Bright and smooth copper deposits were obtained at current densities in the range of 2.0–11.0 A/dm2 from the Cu(CF3COO)2 500 g/l–HCON(CH3)2–citric acid 200 g/l bath at 60 °C, the current efficiencies for cathode and anode being about 75% and above 100% respectively. The cross-section of the copper deposits showed that the deposits have a granular structure. The rate of the electrodeposition of copper from the Cu(CF3COO)2–HCON(CH3)2–citric acid 200 g/l bath at current densities ranging from 1.0 to 3.5 A/dm2 was found to be controlled by the charge–transfer reaction. A black powder nickel deposit was obtained from the Ni(CF3COO)2–HCON(CH3)2 bath. By dissolving NH4Cl, H3BO3, sulfamic acid or CCl3COOH in the bath, adherent bright and smooth nickel deposits were obtained. While the cathode current efficiency was lower in the bath containing sulfamic acid, the anode current efficiency was lower in the bath containing H3BO3 or CCl3COOH. NH4Cl and AlCl3 have the disadvantage that they are dissolved in HCON(CH3)2 only with difficulty. Since the bond between the metallic ion and the solvent in the HCON(CH3)2 bath is stronger than that in the HCONH2 bath, and since dielectric constant of the solvent in the former is lower than that in the latter, metal electrodeposition from the former is more difficult.

Authors: Saxena R S , Bhatia S K 
Published: July 2006

Abstract
Polarographic behaviour of glycol dimercaptoacetate has been studied in 25% ethanol at d.m.e. in the pH range 1.56–11.56 in presence of 0.1 M KNO3. In the acidic media, the current-voltage curves consist of three waves; a prewave due to the adsorption of anodic reaction product at the mercury drop surface, main anodic wave due to the electroxidation of –SH groups and a third wave at more positive potential due to the insoluble film formation on the electrode surface whose solubility depends on pH of the solution. In the alkaline media only two waves, a prewave and the main anodic wave, are observed. The effects of various factors such as different buffer, Hg-pressure, temperature, ethanol and depolarizer concentrations on the wave characteristics have been investigated. The electrode reaction is irreversible at higher pH but in acid media it is reversible and diffusion controlled involving a two electron transfer process, with the formation of (Remark: Graphics omitted.) complex. The overall dissociation constant (pK) of the sulphydryl groups has been found to be 8.20 at 20 °C. At pH 4.80, the maximum number of moles adsorbed on unit area is 6.83×10−10mol/cm2 i.e. 4.12×1014 molecule/ cm2. Adsorption coefficient and molar adsorption energy are calculated to be 1.445×104 and 31.2 kcal/gm mol respectively. The respective values of kinetic parameters, viz. transfer coefficient (α) and formal rate constant (K°b.h) for the irreversible wave at pH 11.56 are 0.76 and 2.6×10−9 cm/s.

Authors: Ohnishi Ryuichiro , Matsui Akira , Tanabe Kozo 
Published: July 2006

Abstract
Catalytic activity of the monohydrates of various metal sulfates for the isomerization of 2-pinene was found to be related to the infrared wave numbers of the rocking mode of the water of crystallization and the transition temperatures from the monohydrates to the anhydrates, but not to the electronegativity of metal ions.

Authors: Suzuki Hitomi , Hanafusa Terukiyo 
Published: July 2006

Abstract
Treatment of pentamethylbenzyl cyanide and bis(cyanomethyl)tetramethylbenzenes with fuming nitric acid in dichloromethane led to the regiospecific nitrooxylation of the methyl group adjacent to the cyanomethyl group, giving the corresponding benzyl nitrates in good yields. On acid hydrolysis, these nitrates were readily converted into 3-isochromanone derivatives.

Abstract
The photoionization efficiency curve of gaseous anthracene was examined by comparing it with the photoemission yield curve of solid anthracene. The direct ionization processes were found to dominate the two curves primarily. Some σ-valence orbitals of this compound were associated with considerably low ionization potentials. The cube law for the photoemission yield near the threshold was also established.

Abstract
Treatments of the normal coordinate and the elastic constant were undertaken for two calcium carbonate crystals. By the use of the least-squares technique, we obtained sets of the force constants which reproduce satisfactorily both the observed vibrational frequencies and the macroscopic elastic constants. The intermolecular interactions, the elastic strains of the internal coordinates, and the nature of the splitting of the normal frequencies in these crystals were briefly discussed.
The Electrochemical Reduction of Purine in Nonaqueous Solvents
Authors: Yao Toshio , Musha S\={o}ichir\={o} 
Published: July 2006

Abstract
The electrochemical reduction of purine, which is the model compound for the reduction of the biologically-important purine bases, has been investigated in nonaqueous solvents (acetonitrile and DMF) by polarography, cyclic voltammetry, controlled potential electrolysis, and the ESR technique. In neutral solutions, purine is initially reduced in a one-electron, diffusion-controlled process at a fairly negative potential to produce an unstable radical anion, which then abstracts a proton from the parent purine to produce a free radical and an electro-inactive purine anion. The free radical is quickly deactivated by fast dimerization to form a purine dimer and by a further one-electron reduction to produce, ultimately, 1,6-dihydropurine. The addition of various acids to purine solutions results in the appearance of a new, drawn-out wave at a more positive potential than the original purine reduction wave, which is attributed to the two-electron reduction of N-protonated purine species to produce 1,6-dihydropurine.

Authors: Isowa Yoshikazu , Ohmori Muneki 
Published: July 2006

Abstract
Optically active Nε-hydroxy-l-lysine monohydrochloride (l-I·HCl) was synthesized from Nε-tosyl-Nε-benzyloxy-l-lysine (l-II) obtained by the procedure employed for the preparation of Nδ-tosyl-Nδ-benzyloxy-l-ornithine. Removal of the protecting groups of l-II was carried out by the following two methods: a) treatment of l-II with boron tris(trifluoroacetate) in trifluoroacetic acid gave l-I in one step, which was isolated as 2-nitroindane-l,3-dione salt; b) deprotection of l-II via Nε-benzyloxy-l-lysine (l-VIII), detosylation with hydrogen bromide in acetic acid and phenol, followed by debenzylation with hydrogenolysis, gave l-I·HCl having properties identical with those of the natural product obtained from mycobactine.
Studies of Acyl and Thioacyl Isocyanates. XIV. The Reactions of Benzoyl and Thiobenzoyl Isocyanates with Hydrazones
Authors: Tsuge Otohiko , Kanemasa Shuji 
Published: July 2006

Abstract
Benzoyl (1) and thiobenzoyl isocyanates (2) reacted with benzaldehyde arylhydrazones and methylhydrazone to give the corresponding semicarbazones as isolated products respectively. In the reactions with acetone arylhydrazones and methylhydrazone, however, the s-triazolidin-5-ones whose structures corresponded to the ring tautomers of semicarbazones, were isolated as sole products from the reaction of 1, and 2 afforded the (4+2) cycloadducts of 2 to the C=N bond of hydrazones and s-triazolidin-5-ones. It has been found that in some cases, the semicarbazones isomerize into their ring tautomers, and the isomerization obeys good first-order kinetics taking into account the equilibrium. Although 1 did not react with p-tosyl- and benzoylhydrazones, 2 easily added to both hydrazones to yield the corresponding (4+2) cycloadducts.

Authors: Tamura Kyoko , Wakahara Akio , Fujiwara Takaji , Tomita Ken-ichi 
Published: July 2006

Abstract
The structure of tyramine hydrochloride has been determined by X-ray diffraction method using the data collected by counter diffractometer techniques. Crystals are orthorhombic, with space group Pbcn, Z=8, a=19.961, b=10.756, and c=8.243 Å. The structure was solved by the direct method with the symbolic addition procedure, and refined by least-squares method. The atoms constituting the tyramine cation lie on the two planes, that is, that of the phenol ring and that of the extended side chain. The dihedral angle between these two planes is 71°. The extended conformation about the C–C bond of aminoethyl group is such that the NH3+ group is trans with respect to the phenol ring. Half-weighted two independent chlorine ions are found on the two-fold axis with distance of 4.5 Å, having some different modes of hydrogen-bonding system for these two ions.
Superacids and Their Derivatives. V. Kinetics and Mechanism of the Cationic Polymerization of 3,3-Bis(chloromethyl)oxacyclobutane Initiated by Ethyl Trifluoromethanesulfonate. Evidence for Ester Type Propagating Species
Authors: Kobayashi Shiro , Danda Hidenori , Saegusa Takeo 
Published: July 2006

Abstract
Kinetic analysis of the cationic ring-opening polymerization of 3,3-bis(chloromethyl)oxacyclobutane (BCMO) initiated by ethyl trifluoromethanesulfonate (EtOSO2CF3) was carried out by direct determination of the instantaneous concentrations of monomer, initiator, and propagating species by means of 1H and 19F NMR spectroscopy. It was established that the polymerization of BCMO proceeds via an ester type propagating species (4). The propagating species of the first (P1*) and subsequent propagations (Pn*, n≥2) were directly observed. The rate constants of initiation (ki) and propagations of the first (kp1), second (kp2) and subsequent steps (kpn, n≥3) were determined. Activation parameters as well as the solvent effect supported the proposed mechanism, in which the rate-determining step is a dipole-dipole reaction between monomer and propagating ester species to form the intermediate cyclic oxonium ions (7, 8, and 10) as unstable transient species.

Published: July 2006

Abstract
New monomeric organoaluminium chelate compounds; N-diethylaluminium N-methyl dialkylthiophosphinic amide and dialkyldithiophosphinate; R2P(S)–X–AlEt2 (X=NMe, S), were prepared. Spectroscopic results of these compounds indicate an intramolecular coordination of sulfur atom of P=S bond to the organoaluminium moiety. Addition reactions of Me2P(S)–NMe–AlEt2 and Et2P(S)–S–AlEt2 with phenyl isocyanate gave the corresponding 1/1 adducts and only small amount of elimination product was obtained. A reaction of Me2P(S)–NMe–AlEt2 with benzaldehyde gave Me2P(S)–NMe–CH(Et)Ph and PhCH=NMe (by two ways of addition-elimination).

Published: July 2006

Abstract
The following sequential polypetides of l-leucine and glycine were synthesized: (Leu3Gly)n, (Leu2Gly)n, (LeuGly)n, and (LeuGly2)n. Polymerization was achieved by self-condensation of the corresponding peptide p-nitrophenyl esters. Hydrolysis of the polypeptides were carried out in 90% aqueous trifluoroacetic acid and the time course of liberation of leucine from each polymer was presented. Apparent first-order rate constants (×102), 1.93, 2.86, 2.91, and 4.4 hr−1 were obtained for liberation of leucine from (Leu3Gly)n, (Leu2Gly)n, (LeuGly)n, and (LeuGly2)n, respectively.

Published: July 2006

Abstract
2E Doubly charged ion mass spectra of forty-six aromatic carbonyl compounds were determined. The spectra are quite different from those of singly charged ions. Several characteristic fragmentations including a novel [M–CO] peak are discussed. It is suggested that certain isomer pairs can be differentiated by comparing these spectra even when their conventional spectra are almost identical.
Isotope Effects in the Reactions of 80Br Activated by Isomeric Transition with Various Deuterated Propanes
Authors: Tachikawa Enzo , Numakura Kenshi 
Published: July 2006

Abstract
Product studies of the reactions of recoil 80Br with propanes in binary mixtures with ethane showed that the difference in the energy-loss efficiency of C3H8 and C3D8 in collision with 80Br was less than 10%. Then, the yields for the substitution of 80Br for atoms or groups have been compared in various deuterated propanes. A reactivity integral-isotope effect has been observed in the yields of products from CD3CD2CD3 and CD3CH2CD3, except in the case of isopropyl bromide from the latter compound. However, it has been observed only in the yield of iso propyl bromide from CH3CD2CH3. These results indicate that the chemical and physical properties of both replaced and residual atoms or groups play a role in the observed isotope effects. With a “complex” formation mechanism, it is suggested that an isotope effect appears mostly when the kinetic energy of the reacting 80Br is at the lower-energy end of the reaction-energy range.
The Surface Activity of Tetra-n-alkylammonium Halides in Aqueous Solutions. The Effect of Hydrophobic Hydration
Authors: Tamaki Kunio 
Published: July 2006

Abstract
Surface tensions are reported for aqueous solutions of a series of homologous tetra-n-alkylammonium chlorides, bromides, and iodides (R4NX) at 25 °C, and the experimental results are discussed with particular reference to the bulk properties of these salts in water. It is found that Me4NX salts are surface inactive in aqueous solutions and that they may be classified as simple salts. On the other hand, it is found that Et4NX and higher homologous salts are surface active in aqueous solutions and that the surface activity increases with the number of carbon atoms in the alkyl chains; thus, they are hydrophobic structure-makers in the water phase. The surface tensions for aqueous solutions of Me4NX salts are only slightly dependent on the kind of counter-ion, such as Cl−, Br−, and I−. In the cases of Et4NX, Pr4NX, and Bu4NX salts, the effectiveness of the anions for the same cation on the surface activity increases progressively in this order: I−&gt;Br−&gt;Cl−.
Contribution of d Orbitals in SiH SiH2, SiH3, and SiH4
Authors: Higuchi Jiro , Kubota Shozo , Kumamoto Toshio , Tokue Ikuo 
Published: July 2006

Abstract
Semi-empirical calculations have been carried out for SiHn (n=1, 2, 3, and 4) adopting the electron pair bond approximation using hybrid orbitals with d orbitals of Si determined by minimizing the energy of each ground state. The results are satisfactory as a whole for explaining the experimental data of these molecules. The contribution of d orbitals obtained is not very large, but it is important in discussing the energy levels and molecular structures of some low-lying electronic states. It is also shown that the maximum overlap method is not always adequate in determining hybrid orbitals including d orbitals.

Published: July 2006

Abstract
The π-allylic palladium(II) complexes of ethyl and benzyl acetoacetate esters react with pyridine and its derivatives to afford the terminal-carbon-bonded complexes PdCl(CH2COCH2COOCH2R)L2, where R=CH3 or C6H5, and L=pyridine or its derivative. The NMR spectra unequivocally establish the bonding type in these complexes. The pyridine and 4-methylpyridine complexes are a mixture of cis and trans isomers in a ratio of 1: 5, while 2-methyl- and 2,6-dimethyl-pyridine complexes are trans exclusively. The relative stabilities of these complexes are compared.
Stereoselectivity in the Formation of Oxalato-l-aspartatoethylenediaminecobalt(III) Complex
Authors: Takeuchi Mitsuaki , Shibata Muraji 
Published: July 2006

Abstract
The complex [Co(ox)(l-aspH)(en)] has been prepared by the reaction of the dioxalatoethylenediaminecobalt-(III) complex with l-aspartic acid and separated into four diastereoisomers by means of ion-exchange chromatography: mer-Δ-, mer-Λ- and facΔ-[Coox(l-aspH)en]·H2O, and facΛ-[Coox(l-aspH)en]·2.5H2O. They were characterized by their absorption, CD and PMR spectra. Stereoselectivity has been found in the mer-Δ and fac-Λ isomers with degrees exceeding 80%. Related isomeric complexes containing l-glutamate or l-leucinate ion in place of l-aspartate have also been investigated, much less selectivity (∼60%) being observed.
Formation of Alkyl Radicals by Photoionization of Alcohol Radicals Trapped in Glassy Matrices
Authors: Shiotani Masaru , Chachaty Claude 
Published: July 2006

Abstract
Experiments were carried out in order to elucidate the formation mechanism of C2H5 · radicals formed by the UV irradiation (250&lt;λ&lt;350 nm) of CH3\dotCHOH radicals. The kinetics of the formation of the C2H5· radical was examined by means of ESR in neutral, acidic, and alkaline ethanol glasses at 77 K. The initial rate of the formation of C2H5· was nearly independent of the concentration of added acid (H2SO4), but it decreased sharply with that of added NaOH. Moreover, the limiting yield of C2H5· decreased with the concentrations of both the acid and the base. Our experimental results suggest that the C2H5· radicals are formed by this reaction:
C_2H_5OH_2^++e^-→C_2H_5·+H_2O
The C2H5OH2+ ion and the electron result from the photoionization of CH3\dotCHOH radicals according to these reactions:
& CH_3\dotCHOH\xrightarrowhv(CH_3CHOH)^++e^-
& (CH_3CHOH)^++C_2H_5OH→CH_3CHO+C_2H_5OH_2^+
