Anion–π interaction augments halide binding in solution

Abstract: 1H NMR spectroscopic data and complementary theoretical predictions suggest that a designed receptor exhibits the anion-pi interaction in solution.

“…[1][2][3][4] In supramolecular chemistry, anion-arene interactions are exploited for the design of artificial receptors exhibiting anion recognition. [5][6][7][8][9][10][11] In biochemistry, Meisenheimer intermediates are involved in enzymatic pathways, the inhibition of which can lead to the treatment of widespread and important diseases. [12][13][14][15][16] Although a large amount of detailed knowledge has been gathered on Meisenheimer complexes in condensed phases, relatively few studies have addressed the issue of anion binding to aromatic rings in the absence of solvation.…”

“…[71] Beispielsweise stellten Berryman und Mitarbeiter zwei Verbindungen mit Sulfonamid-Wasserstoffbrückendonoren her, von denen der eine in Nachbarschaft zu einem Pentafluorphenylring und der andere zu einem nichtfluorierten Phenylring stand (Abbildung 18 a). [72] In [77] Halogenbrücken entstehen durch ein s-Loch am X-Ende der Y-X-Bindung, in das Elektronendichte hineingeschoben werden kann. Die Stärke der Halogenbrücke folgt dem Trend X = I > Br > Cl @ F. Da sich der elektronenarme Bereich am X-Ende der Y-X-Bindung befindet, werden Halogenbrücken als in hohem Maße ausgerichtet angesehen, was für gewçhnlich, aber nicht immer, [78] [79] In Aceton band der Rezeptor Halogenidionen gemäß Cl À > Br À > I À und zeigte keine Affinität für HSO 4 À oder NO 3 À .…”
