Preparation of Magnetic Ionic Liquids Composed of Hybrid-Type Anions

AUSTRALIAN JOURNAL OF CHEMISTRY 65 ( 11 ) 1557 - 1560 2012年

記述言語：英語出版者・発行元：CSIRO PUBLISHING

1-Ethyl-3-methylimidazolium ethylsulfate ([C(2)mim][EtSO4]) was mixed with iron(III) chloride center dot 6H(2)O to give a magnetic ionic liquid composed of the hybrid-type anion, [C(2)mim][FeCl3 center dot EtSO4], which showed a slightly different magnetic property than [C(2)mim][FeCl4]. On the other hand, reaction of [C(2)mim][EtSO4] with cobalt(II) chloride hydrate formed [C(2)mim](2)[(CoCl4)-Cl-II], the structure of which was characterised by X-ray crystallographic analysis.

2-Diphenylphosphanyl-4-pyridyl(dimethyl) amine as an effective ligand for the ruthenium(II) complex catalyzed homogeneous hydration of nitriles under neutral conditions

Makoto Muranaka, Isao Hyodo, Wataru Okumura, Toshiyuki Oshiki

CATALYSIS TODAY 164 ( 1 ) 552 - 555 2011年4月

記述言語：英語出版者・発行元：ELSEVIER SCIENCE BV

New homogeneous catalyst comprised of [Ru(methallyl)(2)(cod)] (cod = 1,5-cyclooctadiene) (1) and 2-diphenylphosphanyl-4-pyridyl(dimethyl) amine (2) is shown to efficiently catalyze the hydration of various nitriles under neutral conditions. The hydration proceeds in the presence of 0.5 mol% of the ruthenium catalyst at 80 degrees C in 1,2-dimethoxyethane solution and the corresponding amide is obtained within few hours without the formation of by products. Comparison of some phosphine ligands for the hydration reveals that the dimethylamino moiety of 2 improves the catalytic performance dramatically. (C) 2010 Elsevier B. V. All rights reserved.

Tantalum Complexes Incorporating Tris(pyrazolyl)Borate Ligands: Syntheses, Structures, and Ethylene Polymerization Behavior

Four new Ta complexes bearing tris(pyrazolyl)borate ligands, Tp*TaCl(eta(2)-3-hexyne)(benzyl) [1; Tp* = HB(3,5-dimethylpyrazolyl)(3)(-)], Tp(Ms)*TaCl(2)(eta(2)-3-hexyne) [2; Tp(Ms)* = HB(3-mesitylpyrazolyl)(2)(5-mesitylpyrazolyl)(-)], Tp(Ms)*TaCl(2) (=N-2,6-(i)Pr(2)C(6)H(3)) (3), and Tp(Ms)TaCl(2) (=N-(t)Bu) [4; Tp(Ms) = HB(3-mesitylpyrazolyl)(3)(-)] were prepared in moderate to high yields from appropriate TaCl(3)(R) (R; eta(2)-3-hexyne, =N-2,6-(i)Pr(2)C(6)H(3), =N-(t)Bu) species and the potassium or thallium salt of the corresponding tris(pyrazolyl)borate ligand. The molecular structures of complexes 3 and 4 established by X-ray analyses showed that these complexes adopted a distorted octahedral geometry in which the Ta metal is coordinated by three N atoms of the tris(pyrazolyl)borate ligand (facial coordination), two cis-located Cl atoms, and the imido group. In combination with dried methylaluminoxane or (i)Bu(3)Al/Ph(3)CB(C(6)F(5))(4), complexes 1-4 were all active for ethylene polymerization and produced low to very high molecular weight, highly linear polyethylenes. In particular, upon activation with (i)Bu(3)Al/Ph(3)CB(C(6)F(5))(4), high activities were observed for complexes 3 and 4, which possess the sterically encumbered mesityl-substituted tris(pyrazolyl)borate ligand and the imido group as all auxiliary ligand. The activities, 25.7 kg-PE/mmol-Ta.h (complex 3) and 17.1 kg-PE/mmol-Ta.h (complex 4). represent some of the highest values reported to date for Ta-based catalysts. These highly active Ta-based catalysts were long-lived and maintained a practically steady ethylene uptake for 30 min at 80 degrees C.

The Hydration of Nitriles Catalyzed by the Combination of Palladium Nanoparticles and Copper Compounds

Akinori Ishizuka, Yoshiaki Nakazaki, Toshiyuki Oshiki

CHEMISTRY LETTERS 38 ( 4 ) 360 - 361 2009年4月

記述言語：英語出版者・発行元：CHEMICAL SOC JAPAN

New catalysts based on Pd nanoparticles for the hydration of nitrites to amides were investigated. Copper compounds containing oxygen acted as effective promoters in the catalytic system. The catalysts could be used to prepare aromatic and aliphatic amides from the corresponding nitrites. Chloride ions significantly inhibited the catalytic performance.
