Journal ArticleDOI
Structures of the reactive intermediates in organocatalysis with diarylprolinol ethers
Uroš Grošelj,Dieter Seebach,D. Michael Badine,W. Bernd Schweizer,Albert K. Beck,Ingo Krossing,Petra Klose,Yujiro Hayashi,Tadafumi Uchimaru +8 more
TL;DR: In this article, the structure of the reactive intermediates (enamines and iminium ions) of organocatalysis with diarylprolinol derivatives have been determined by melting/decomposition points, [α]D, elemental analysis, IR and NMR spectroscopy, and high resolution mass spectrometry (HR-MS).
Journal ArticleDOI
Inhibiting Polysulfide Shuttle in Lithium–Sulfur Batteries through Low‐Ion‐Pairing Salts and a Triflamide Solvent
Abhinandan Shyamsunder,Witali Beichel,Petra Klose,Quan Pang,Harald Scherer,Anke Hoffmann,Graham K. Murphy,Ingo Krossing,Linda F. Nazar +8 more
TL;DR: The first new electrolyte based on a unique combination of a relatively hydrophobic sulfonamide solvent and a low ion-pairing salt, which inhibits the polysulfide shuttle, is presented.
Journal ArticleDOI
Synthesis of Room‐Temperature Ionic Liquids with the Weakly Coordinating [Al(ORF)4]− Anion (RF=C(H)(CF3)2) and the Determination of Their Principal Physical Properties
Safak Bulut,Petra Klose,Mian-Mian Huang,Hermann Weingärtner,Paul J. Dyson,Gábor Laurenczy,Christian Friedrich,Jakob Menz,Klaus Kümmerer,Ingo Krossing +9 more
TL;DR: The determination of hydrogen gas solubility in [Al(hfip)(4)](-) RTILs by high-pressure NMR spectroscopy revealed very high hydrogen solubilities at 25 °C and 1 atm, indicating the significant potential of this class of ILs in manifold applications.
Journal ArticleDOI
Size matters! On the way to ionic liquid systems without ion pairing.
Alexander B. A. Rupp,Nataliya Roznyatovskaya,Harald Scherer,Witali Beichel,Petra Klose,Carola Sturm,Anke Hoffmann,Jens Tübke,Thorsten Koslowski,Ingo Krossing +9 more
TL;DR: It was concluded that [Al(hfip)4 ](-) -based ILs come close to systems without any interactions, and this hypothesis is underlined with a Hirshfeld analysis.
Journal ArticleDOI
Na[B(hfip)4] (hfip = OC(H)(CF3)2): a weakly coordinating anion salt and its first application to prepare ionic liquids
TL;DR: The fast, high yield synthesis and full characterization of Na[B(hfip)(4)](-) ILs from NaBH(4) and hexafluoroisopropanol and they have good stability against humidity/water and may be classified as "good".
