Authors: Tsuchiya Ryokichi , Uehara Akira , Kyuno Eishin 
Published: July 2006

Abstract
[Cr(NH3)6][Al(nta)2]· 4H2O was newly prepared, of which solid-phase thermal reaction was investigated by means of derivatography. The results showed that the complex converts finally into Al[Cr(nta)2].

CARBOXYLATION REACTION OF DIISOBUTENE AND 1-OCTENE WITH CARBON MONOXIDE USING A Cu(I)CARBONYL BF3–H2O CATALYST SYSTEM
Authors: Yoneda Norihiko , Fukuhara Tsuyoshi , Takahashi Yukio , Suzuki Akira 
Published: July 2006

Abstract
The carboxylation of diisobutene and 1-octene with carbon monoxide using Cu(I)carbonyl as catalyst in BF3–H2O takes place smoothly at room temperature to produce tertiary carboxylic acids in high yields. The present procedure is superior to that using the same catalyst in concentrated H2SO4, both from a point of view of high yield of carboxylic acids and ready separation of such acids from the catalyst layer.

Authors: Tsukada Harumichi , Shimanouchi Hirotaka , Sasada Yoshio 
Published: July 2006

Abstract
The crystal structure of anhydrous diphenylcyclopropenone was determined and the structural features are compared with those in its monohydrate. The systematic variation of the molecular geometry found is attributable to the contribution from a dipolar ionic form, enhanced by the formation of the hydrogen bond.
ENDOR STUDY OF HINDERED INTERNAL ROTATION OF THE ALKYL GROUP IN THE 4,4′-DIISOPROPYL BIPHENYL ANION RADICAL
Authors: Nemoto Fujito , Shimoda Fumio , Ishizu Kazuhiko 
Published: July 2006

Abstract
Utilizing ENDOR observations for the 4,4′-diisopropylbiphenyl anion, the β-proton coupling constants were determined and their temperature dependence was investigated. The positive temperature dependence of the β-proton coupling constant was interpreted utilizing a revised model of restricted rotation for isopropyl groups (see Fig.3-b). The energy difference, Eo between the two equilibrium states of this restricted rotational system was estimated to be 0.4 Kcal/mol.

POLAROGRAPHY OF THE CIS-DICYANOBIS(ETHYLENEDIAMINE)CHROMIUM(III) COMPLEX
Authors: Maki Nobufumi 
Published: July 2006

Abstract
The cis-[CrIII(CN)2en2]ClO4 complex gave rise to a two-stepped wave responsible for the reductions of Cr(III) to Cr(II) and to Cr(I) state at the dropping mercury electrode(DME) in dimethyl sulfoxide(DMSO). The reduction of the first step is reversible, while that of the second is quasi-reversible. The standard redox potential of the Cr(III)/Cr(II) couple was −1.586 V (vs. aq. SCE). In aqueous solutions containing 0.5 M Na2SO4 or acetate buffer, however, the cis-[Cr(CN)2en2]+ ion gave rise to only one irreversible wave for the reduction of Cr(III) to Cr(II) even in the presence of ethylenediamine in a large excess. Unlike the cases of cis-[Co(CN)2en2]+ and cis-[Co(CN)2dip2]+, the aquation of the resulting Cr(II) complex occurs so fast that a cyanide disproportionate reaction cannot be observed under such conditions.

Authors: Okawa Hisashi , Tanaka Mitsunori , Kida Sigeo 
Published: July 2006

Abstract

This complex has [CuN2O2]- and [NiO6]-chromophores and two metal ions are connected by the phenolic oxygens. The magnetic susceptibility was well explained in terms of the equation for the high-spin nickel(II)-copper(II) cluster.

THE PHOTOCHEMISTRY OF 2-QUINOLINECARBONITRILES. III. THE BENZOPHENONE-SENSITIZED REACTION
Authors: Hata Norisuke , Ohtsuka Ryoichi 
Published: July 2006

Abstract
Benzophenone-sensitization of 2-quinolinecarbonitrile (1), 4-methylquinoline-2-carbonitrile (2), or 4-chloroquinoline-2-carbonitrile (3) in ethanol resulted in the formation of triazapentaphene (1a), 2-(hydroxydiphenylmethyl)-4-methylquinoline (2a), or 4,4′- bi-(2,2′-dicyano)quinoline (3a) in a good yield. It appears that 1 → 1a proceeds through the T1 (π,π*) state populated by an energy-transfer mechanism, whereas 2 → 2a or 3 → 3a occurs via the ketyl radical of benzophenone which exchanges a hydrogen atom with 2 or 3 in the ground state.

QUENCHING OF FLUORESCENCE OF POLYESTERS HAVING PENDANT ANTHRYL GROUPS BY POLYESTERS HAVING PENDANT N,N-DIMETHYLANILINO GROUPS
Authors: Tazuke Shigeo , Sato Kaname , Banba Fumio 
Published: July 2006

Abstract
Fluorescence of various polyesters prepared from 2-(9-anthryl)methylpropane-1,3-diol was quenched by various polyesters prepared from 2-(4-dimethylaminobenzyl)propane-1,3-diol. The sequence of quenching constants(Kq) was discussed with special reference to the polymer structures of fluorescers and quenchers. When terephthalate groups were incorporated in the main chain of quencher, Kq increased very much, which was interpreted by cooperative quenching action of donor(amine) and acceptor(terephthalate). This concept was unequivocally evidenced by separate experiments.

Published: July 2006

Abstract
The Mössbauer parameters of bis(tri-n-butyltin) sulfate, selenate, and chromate have been determined in order to elucidate the intermolecular interaction of such species in solid state. The absolute values of recoilfree fraction have been estimated in the temperature range from 80 to 200 K and the mean square displacement of tin atom has been determined. From the results, as well as from the temperature dependence of quadrupole split line asymmetry, non-polymeric structure is inferred for those three compounds.

Authors: Goto Masafumi , Fujii Tsuneo , Sakai Tomoya 
Published: July 2006

Abstract
The addition of [Co(II)(en)2Cl]+ accelerated the isomerization of cis-[Co(III)(en)2Cl2]+ to its trans-isomer in methanol. The reaction by use of [Co(II)(en)2Br]+ or [Co(II)(l-chxn)2Cl]+ instead of [Co(II)(en)2Cl]+ produced trans-[Co(III)(en)2BrCl]+ or trans-[Co(III)(l-chxn)2Cl2]+, respectively. These evidences demonstrated the inner-sphere electron transfer from Co(II) to Co(III) in the acceleration mechanism of the title isomerization reaction.
