Rhodium-catalyzed odorless synthesis of diaryl sulfides from borylarenes and S-aryl thiosulfonates.

Chemical communications (Cambridge, England)

Kanemoto K, Sugimura Y, Shimizu S, Yoshida S, Hosoya T.
PMID: 28920976
Chem Commun (Camb). 2017 Sep 26;53(77):10640-10643. doi: 10.1039/c7cc05868c.

Various diaryl sulfides, including heteroaryl- and nitrogen-containing sulfides, have been efficiently prepared by rhodium-catalyzed odorless deborylative arylthiolation of organoborons with S-aryl thiosulfonates. The ready availability of starting materials and further transformation of sulfides have rendered a diverse range of...

Rev Sci Instrum. 2016 Apr;87(4):043502. doi: 10.1063/1.4944864.

Hard X-ray spectroscopy is an essential diagnostics used to understand physical processes that take place in high energy density plasmas produced by intense laser-plasma interactions. A bundle of hard X-ray detectors, of which the responses have different energy thresholds,...

Correlations between clinical parameters in implant maintenance patients: analysis among healthy and history-of-periodontitis groups.

International journal of implant dentistry

Seki K, Nakabayashi S, Tanabe N, Kamimoto A, Hagiwara Y.
PMID: 29086151
Int J Implant Dent. 2017 Oct 30;3(1):45. doi: 10.1186/s40729-017-0108-0.

BACKGROUND: The pathophysiology and pathology of peri-implantitis remain unclear; however, its similarity to periodontitis has been described. The evaluation of peri-implant tissue and the diagnostic criteria of peri-implant disease are not currently standardized as they are for periodontitis. In...

True Vapor-Liquid-Solid Process Suppresses Unintentional Carrier Doping of Single Crystalline Metal Oxide Nanowires.

Nano letters

Anzai H, Suzuki M, Nagashima K, Kanai M, Zhu Z, He Y, Boudot M, Zhang G, Takahashi T, Kanemoto K, Seki T, Shibata N, Yanagida T.
PMID: 28671477
Nano Lett. 2017 Aug 09;17(8):4698-4705. doi: 10.1021/acs.nanolett.7b01362. Epub 2017 Jul 07.

Single crystalline nanowires composed of semiconducting metal oxides formed via a vapor-liquid-solid (VLS) process exhibit an electrical conductivity even without an intentional carrier doping, although these stoichiometric metal oxides are ideally insulators. Suppressing this unintentional doping effect has been...

Scientific reports

Makino F, Shen D, Kajimura N, Kawamoto A, Pissaridou P, Oswin H, Pain M, Murillo I, Namba K, Blocker AJ.
PMID: 27686865
Sci Rep. 2016 Sep 30;6:33341. doi: 10.1038/srep33341.

Type III secretion systems (T3SSs) are essential devices in the virulence of many Gram-negative bacterial pathogens. They mediate injection of protein effectors of virulence from bacteria into eukaryotic host cells to manipulate them during infection. T3SSs involved in virulence...

Facile synthesis, crystal structures, and high-spin cationic states of all-para-brominated oligo(N-phenyl-m-aniline)s.

The Journal of organic chemistry

Ito A, Ino H, Tanaka K, Kanemoto K, Kato T.
PMID: 11798322
J Org Chem. 2002 Jan 25;67(2):491-8. doi: 10.1021/jo0160571.

Syntheses of both the dimer (3) and the trimer (4) of all-para-brominated poly(N-phenyl-m-aniline)s (2c) were achieved in a one-pot procedure from the parent nonbrominated oligomers and benzyltrimethylammonium tribromide [(BTMA)Br(3)]. An X-ray crystallographic analysis revealed that 4 has a U-shaped...

Examination of the charge-sensitive vibrational modes in bis(ethylenedithio)tetrathiafulvalene.

Lithiated 1,3-diene-iron complexes undergo a CO insertion in the presence of trimethyl phosphite via a ferrate intermediate to give 3-formyl or 3-acetyl-1,3-diene-Fe(CO)(2)P(OMe)(3) complexes. Formylation proceeds when the reaction is quenched by a strong Brønsted acid, whereas the ketone is...
