Photoresponsive Ionic Liquids with an Azobenzene Moiety

Autor: Toyokazu Yamauchi, Satoshi Kitaoka, Yuichi Ishikawa, Thomas Harran, Kaoru Nobuoka

Publikováno v: Chemistry Letters. 45:433-435

We examined photoresponsive ionic liquids containing an azobenzene moiety. Ionic liquids with a p,p′-azobenzene or o,p′-tetrafluoroazobenzene moiety exhibit a reversible solid-to-liquid phase trans...

Chiral ionic liquids, starting from (S)-proline, have been prepared and evaluated the ability of a chiral catalyst. In Michael reaction of trans-β-nitrostyrene and cyclohexanone, all the reactions were carried out under homogeneous conditions withou

Camphor Ionic Liquid: Correlation between Stereoselectivity and Cation−Anion Interaction

Autor: Masashi Iio, Kazuya Kunimitsu, Satoshi Kitaoka, Yuichi Ishikawa, and Akihiro Wakisaka, Kaoru Nobuoka, Thomas Harran

Publikováno v: The Journal of Organic Chemistry. 70:10106-10108

[structure: see text] As a halogen-free anion for an imidazolium room temperature ionic liquid, the use of a camphorsulfonate causes an increase in the number of free (naked) imidazolium cations, which produces an effective endo/exo stereoselective D

Solute-solvent interactions in imidazolium camphorsulfonate ionic liquids

Autor: Masashi Iio, Yuichi Ishikawa, Kaoru Nobuoka, Satoshi Kitaoka, Thomas Harran

Publikováno v: Physical chemistry chemical physics : PCCP. 9(44)

We directly observe the interaction between 1-butyl-3-methylimidazolium (bmim) or 1-butyl-2,3-dimethylimidazolium (bm(2)im) and the solute, ethyl acrylate (EA), which is the popular dienophile in the Diels-Alder reaction and an H-bonding acceptor, by

Stereoselectivity of the Diels–Alder reaction in ionic liquids with cyano moieties: effect of the charge delocalization of anions on the relation of solvent–solvent and solute–solvent interactions

Autor: Yusuke Maki, Yuichi Ishikawa, Kaoru Nobuoka, Atsuki Yanagisako, Satoshi Kitaoka, Thomas Harran

Publikováno v: RSC Advances. 3:19632

In imidazolium ILs, the negative charge delocalization induced by multiple electron-withdrawing cyano groups can be useful in regulating the microscopic environment in imidazolium ILs. For this anion design, the ion–counterion (solvent–solvent) i
