Cobalt-catalyzed Heck-type reaction of alkyl halides with styrenes.
TL;DR: A cobalt complex, CoCl2[1,6-bis(diphenylphosphino)hexane], catalyzes an alkylation reaction of styrenes in the presence of Me3SiCH2MgCl in ether to yield beta-alkylstyrenes.
Journal ArticleDOI
Powerful solvent effect of water in radical reaction: Triethylborane-induced atom-transfer radical cyclization in water
Hideki Yorimitsu,Tomoaki Nakamura,Hiroshi Shinokubo,Koichiro Oshima,Kiyoyuki Omoto,Hiroshi Fujimoto +5 more
TL;DR: In this paper, a triethylborane-induced atom-transfer radical cyclization of allyl iodoacetate (3a) is described and the remarkable solvent effect of water was observed in this reaction.
Journal ArticleDOI
Cobalt-Catalyzed Trimethylsilylmethylmagnesium-Promoted Radical Alkenylation of Alkyl Halides: A Complement to the Heck Reaction
Walter Affo,Hirohisa Ohmiya,Takuma Fujioka,Yousuke Ikeda,Tomoaki Nakamura,Hideki Yorimitsu,Koichiro Oshima,Yuki Imamura,Tsutomu Mizuta,Katsuhiko Miyoshi +9 more
TL;DR: Crystallographic and spectroscopic investigations on cobalt complexes reveal that the reaction would begin with single electron transfer from an electron-rich (diphosphine)bis(trimethylsilylmethyl)cobalt(II) complex followed by reductive elimination to yield 1,2-bis(diphenylphosphino)ethane and a (d PH2) complex.
Journal ArticleDOI
Remote asymmetric induction with vinylketene silyl n,o-acetal.
Shin Ichi Shirokawa,Masato Kamiyama,Tomoaki Nakamura,Masakazu Okada,Atsuo Nakazaki,Seijiro Hosokawa,Susumu Kobayashi +6 more
TL;DR: The present vinylogous Mukaiyama aldol reaction provides a unique and effective means of controlling remote asymmetric induction and can provide a one-step construction of delta-hydroxy- alpha,gamma-dimethyl-alpha,beta-unsaturated carbonyl unit that is seen in many natural polyketide products.
Journal ArticleDOI
Functionalization on Silica Gel with Allylsilanes. A New Method of Covalent Attachment of Organic Functional Groups on Silica Gel
Toyoshi Shimada,Kazuko Aoki,Yo Shinoda,Tomoaki Nakamura,Norihito Tokunaga,Shinji Inagaki,Tamio Hayashi +6 more
TL;DR: Treatment of an (allyl)organosilane with silica gel in refluxing toluene brought about deallylation forming an Si-O-Si bond with the silicon on thesilica gel, providing a new reliable method for the functionalization of a silica Gel surface.
