A Reductive Benzylation for Benzenes Using Aroyl Chlorides and Triethylsilane Catalyzed by Aluminosilicate-Stabilized Silyl Cations on Montmorillonite
Autor: Makoto Onaka, Yoshiki Tanaka, Shintaro Shibata, Kimiko Hashimoto, Yoichi Masui
Publikováno v: Synlett. 33:2026-2032
We discovered that the aluminosilicate-stabilized silyl cations, which were created from a solid-acid catalyst, the proton-exchanged montmorillonite, and Et3SiH, efficiently promoted the reductive benzylation of benzenes with aromatic carboxylic acid

Coordination Behaviors of Diphenylketene Adsorbed in the Nanocages of Zeolite NaY and AgY
Autor: Yoichi Masui, S. Shibata, Makoto Onaka
Publikováno v: Bulletin of the Chemical Society of Japan. 93:663-670
We investigated in detail how polar cumulene molecules like diphenylketene were accommodated in faujasite zeolite pores based on 13C CP/MAS and DD/MAS NMR analyses as well as quantum chemical calcu...

Performance and hematology of pacu fed diets supplemented with vitamins C and/or E Desempenho e hematologia do pacu alimentado com dietas suplementadas com vitaminas C e/ou E
Autor: Fabiana Garcia, Fabiana Pilarski, Eduardo Makoto Onaka, Flávio Ruas de Moraes
Publikováno v: Scientia Agricola, Vol 68, Iss 3, Pp 314-319 (2011)
Pacu (Piaractus mesopotamicus Holmberg, 1887) is a valued Brazilian fish species for aquaculture. This is highly susceptible to disease, and feed supplementations for pacu can be a very important strategy to prevent disease incidence in fish farms. T

Ruthenium(II)−Bipyridine/NanoC3 N4 Hybrids: Tunable Photochemical Properties by Using Exchangeable Alkali Metal Cations
Autor: D. Tatsumi, Hiromi Yamashita, Tomoyuki Iwamoto, Yoichi Masui, Makoto Onaka, Kohsuke Mori
Publikováno v: Chemistry - An Asian Journal. 13:1348-1356
A series of nanoporous carbon nitrides that contained a range of alkali metal cations (M@nanoC3 N4 : M=Li+ , Na+ , K+ , Rb+ , and Cs+ ) have been successfully synthesized from as-synthesized g-C3 N4 by delamination with concentrated sulfuric acid, fo

Molecular Behaviors of Formaldehyde Encapsulated in Supercages of Zeolite NaY with Different Loadings and its Intrinsic Reactivity for the Carbonyl-ene Reaction with α-Methylstyrene
Autor: Kei-ichi Sato, Makoto Onaka, Yoichi Masui
Publikováno v: Bulletin of the Chemical Society of Japan. 90:1318-1324
The reactivity of formaldehyde (HCHO) adsorbed in the supercages of zeolite NaY toward α-methylstyrene for the carbonyl-ene reaction was very dependent on the loading amount of HCHO in the NaY pores. We first prepared a series of NaY samples with di

Reversible Generation of Labile Secondary Carbocations from Alcohols in the Nanospace of H-Mordenite and Their Long-Lasting Preservation at Ambient Temperature
Autor: Yoichi Masui, Taiki Hattori, Makoto Onaka
Publikováno v: Journal of the American Chemical Society. 139:8612-8620
Secondary carbocations are rarely observed spectrometrically for prolonged durations at ambient temperatures because of their instability. In this study, when 4,4′-difluorobenzhydrol (1) was mixed with H-mordenite (H-Mor), the 4,4′-difluorodiphen

Autor: Yoichi Masui, Taiki Hattori, Masashi Asano, Makoto Onaka, Michael Andreas Tandiary, Satoshi Takehira
Publikováno v: Tetrahedron Letters. 58:1925-1928
The solid acid, tin hydroxide-embedded montmorillonite, catalyzes the unprecedented alkylation of various silicon enolates with primary, secondary and tertiary benzylic alcohols as well as secondary allylic alcohols. The acid catalysis of Sn-Mont was
