Journal ArticleDOI
Heterogeneous Pd/C-catalyzed ligand-free, room-temperature Suzuki-Miyaura coupling reactions in aqueous media.

TL;DR: Inductively coupled plasma (ICP) mass-spectrometric analysis of the filtrate from the reaction mixture of 4-bromonitrobenzene with phenylboronic acid demonstrated that the palladium metal hardly leached into the solution within the limits of the detector, thus suggesting that the present Suzuki-Miyaura reaction proceeded by heterogeneous catalysis.
Journal ArticleDOI
Facile and Clean Oxidation of Alcohols in Water Using Hypervalent Iodine(III) Reagents
Journal ArticleDOI
Efficient and Practical Arene Hydrogenation by Heterogeneous Catalysts under Mild Conditions
Tomohiro Maegawa,Akira Akashi,Kiichiro Yaguchi,Yohei Iwasaki,Masahiro Shigetsura,Yasunari Monguchi,Hironao Sajiki +6 more
TL;DR: The use of Ru /C, less expensive than Rh/C, affords an effective and practical method for the hydrogenation of arenes including phenols.
Journal ArticleDOI
Pd/C-catalyzed chemoselective hydrogenation in the presence of diphenylsulfide.
TL;DR: A Pd/C-catalyzed chemoselective hydrogenation using diphenylsulfide as a catalyst poison has been developed and selectively hydrogenates olefin and acetylene functionalities without hydrogenolysis of aromatic carbonyls and halogens, benzyl esters, and N-Cbz protective groups.
Journal ArticleDOI
Ligand-free Pd/C-catalyzed Suzuki–Miyaura coupling reaction for the synthesis of heterobiaryl derivatives
Yoshiaki Kitamura,Satoko Sako,Takahiro Udzu,Azusa Tsutsui,Tomohiro Maegawa,Yasunari Monguchi,Hironao Sajiki +6 more
TL;DR: A mild and efficient protocol for the ligand-free and heterogeneous Pd/C-catalyzed hetero Suzuki-Miyaura coupling reaction that allows for the synthesis of both hetero Daryl-aryl and heteroaryl-heteroaryl derivatives in good to excellent yields.
