Design and Synthesis of a Chiral Halogen-Bond Donor with a Sp3-Hybridized Carbon–Iodine Moiety in a Chiral Fluorobissulfonyl Scaffold

open access: yesMolecules, 2020
The first example of a chiral halogen-bond donor with a sp3-hybridized carbon–iodine moiety in a fluorobissulfonyl scaffold is described. The binaphthyl backbone was designed as a chiral source and the chiral halogen-bond donor (R)-1 was synthesized from

The Effect of Intermolecular Halogen Bond on 19F DNP Enhancement in 1, 4-Diiodotetrafluorobenzene/4-OH-TEMPO Supramolecular Assembly

open access: yesChinese Journal of Magnetic Resonance, 2017
Halogen bond, as hydrogen bond, is a non-covalent bond. Dynamic nuclear polarization (DNP) technique has been used previously to study hydrogen bonds-mediated intermolecular interactions. However, no study has been carried out so far to study the halogen

Hybrid Molecular Dynamics for Elucidating Cooperativity Between Halogen Bond and Water Molecules During the Interaction of p53-Y220C and the PhiKan5196 Complex

open access: yesFrontiers in Chemistry, 2020
The cooperativity between hydrogen and halogen bonds plays an important role in rational drug design. However, mimicking the dynamic cooperation between these bonds is a challenging issue, which has impeded the development of the halogen bond force field.

The halogen bond with isocyano carbon reduces isocyanide odor

open access: yesNature Communications, 2020
Predominantly, carbon atoms of various species function as acceptors of noncovalent interactions when they are part of a π-system. Here, we report on the discovery of a halogen bond involving the isocyano carbon lone pair.

Halogen bonding and chalcogen bonding mediated sensing

open access: yesChemical Science, 2022
Sigma–hole mediated detection of anions is rapidly emerging as a new paradigm in supramolecular sensor chemistry. Herein, we provide an overview of this field including halogen bonding and chalcogen bonding optical, electrochemical and other sensors.

Complementary, Cooperative Ditopic Halogen Bonding and Electron Donor-Acceptor π-π Complexation in the Formation of Cocrystals

open access: yesMolecules, 2022
This study expands and combines concepts from two of our earlier studies. One study reported the complementary halogen bonding and π-π charge transfer complexation observed between isomeric electron rich 4-N,N-dimethylaminophenylethynylpyridines and the ...

Theoretical, Solid-State and Solution Quantification of the Hydrogen Bond Enhanced Halogen Bond.

open access: yesAngewandte Chemie, 2020
Proximal noncovalent forces are commonplace in natural systems and understanding the consequences of their juxtaposition is critical. This paper experimentally quantifies for the first time a Hydrogen Bond enhanced Halogen Bond (HBeXB) without the ...

Transmembrane Halogen-Bonding Cascades

open access: yesJournal of the American Chemical Society, 2013
Halogen bonds have recently been introduced as ideal to transport anions across lipid bilayer membranes. However, activities obtained with small transporters were not impressive, and cyclic arrays of strong halogen-bond donors above a calix[4]arene scaffold gave even weaker activities. Here, we report that their linear alignment for anion hopping along

Cooperativity of halogen bonds – enhancing halogen-bond donating ability of halogenated pyridines through halogen bonding with N-haloimides [PDF]

open access: yesActa Crystallographica Section A Foundations and Advances, 2018
N-halogenated imides, common halogenating agents in organic synthesis, have recently been marked as extremely strong halogen donors. In previous studies we have demonstrated that N-halogenated succinimides form extremely short XBs with halogen bond energies between 20 and 60 kJ mol–1, depending on the pyridine basicity and the halogen atom. In light of

Neutral Chiral Tetrakis‐Iodo‐Triazole Halogen‐Bond Donor for Chiral Recognition and Enantioselective Catalysis

open access: yesChemistry, 2020
Halogen bonding represents a powerful tool in the field of noncovalent interactions. However, applications in enantioselective recognition and catalysis remain almost nonexistent, due in part to the distinct features of halogen bonds, including long ...
