Low-Temperature Active Pt-catalysts Supported on Mesoporous Silica and Metal-Silicates for Cleaning Diesel-NOx Exhausts

Autor: Mitsuo Konishi, Tamikuni Komatsu, Takashi Shirai, Keizo Tomokuni

Publikováno v: International Journal of Chemistry. 4

New Pt-catalysts supported on mesoporous silica (MPS) and metal-silicates, which have high de-NOx capabilities over 70 % in NOx-conversion at temperatures around 170 under lean conditions, were developed. A new prototype honeycomb supporting Pt-catal

Chiral β-dimethylaminoalkylphosphines. Highly efficient ligands for a nickel complex catalyzed asymmetric grignard cross-coupling reaction

Autor: Tamio Hayashi, Makoto Kumada, Mitsuo Konishi, Motoo Fukushima

Publikováno v: Tetrahedron Letters. 21:79-82

Chiral β-dimethylaminoalkylphosphines were prepared starting with amino acids, (S)-alanine, (S)-phenylalanine, (R)-phenylglycine, (S)-valine, and (R)-tert-leucine. The chiral phosphines were found to be highly efficient ligands for a nickel catalyze

Cross-coupling reaction of secondary alkyl grignard reagents with allylic alcohols catalyzed by dichloro[1,1′-bis(diphenylphosphino)-ferrocene]palladium(II)

Autor: Tamio Hayashi, Makoto Kumada, Mitsuo Konishi

Publikováno v: Journal of Organometallic Chemistry. 186:C1-C4

Dichloro[1,1′-bis(diphenylphosphino)ferrocene]palladium(II) was found to catalyze the reaction of allylic alcohols with 2-octylmagnesium chloride and 1-phenylethylmagnesium chloride to give the corresponding cross-coupling products in high yields.

THERMAL AND PHOTOSENSITIZED DECOMPOSITION OF DIMERIC VALEROPHENONE PEROXIDE FORMED BY OZONATION OF VALEROPHENONE OXIME ETHER

Autor: Teruo Matsuura, Mitsuo Konishi, Yoshikatsu Ito

Publikováno v: Photochemistry and Photobiology. 30:53-57

— Ozonation of valerophenone oxime o-methyl ether (4) produced a stereoisomeric mixture of crystalline dimeric valerophenone peroxides, 5a and 5b. N-n-butyl-N-methoxybenzamide (6) and N-methoxy-N-phenylvaleramide (7) along with valerophenone (1). T
