An overview of halogen bonding
Journal of Molecular Modeling, 2006Halogen bonding (XB) is a type of noncovalent interaction between a halogen atom X in one molecule and a negative site in another. X can be chlorine, bromine or iodine.

Halogen Bonding Molecular Capsules
Angewandte Chemie - International Edition, 2015AbstractMolecular capsules based solely on the interaction of halogen bonding (XB) are presented along with their host–guest binding properties in solution. The first example of a well‐defined four‐point XB supramolecular system is realized by decorating resorcin[4]arene cavitands with polarized halogen atoms for dimerization with tetra(4‐pyridyl ...

Clˉ as the halogen bond acceptor: studies on strong halogen bonds
Structural Chemistry, 2017The Clˉ anion as the halogen bond acceptor, the diiodotetrafluoroethane I(CF2)2I and its derivatives I(MF2)nI (M = C, Si, Ge, Sn) as the halogen bond donor, and the strong halogen bonds could be formed. The halogen bonds between I(MF2)nI and Clˉ have been designed and investigated by Moller–Plesset perturbation/aug-cc-pVDZ calculations together with ...

Halogens are atypical elements in biology, but are common as substituents in ligands, including thyroid hormones and inhibitors, which bind specifically to proteins and nucleic acids. The short-range, stabilizing interactions of halogens - now seen as relatively common in biology - conform generally to halogen bonds characterized in small molecule ...

Halogen Bonding in Supramolecular Synthesis
2014Supramolecular synthesis is typically limited to one-pot reactions because of the reversibility of non-covalent bonds, and to overcome this restriction we need to be able to rank the relative structural importance of such interactions and build synthetic methods to utilize synthons which can operate side-by-side without interference. Halogen bonds have

Chalcogen Bond: A Sister Noncovalent Bond to Halogen Bond
The Journal of Physical Chemistry A, 2009A sister noncovalent bond to halogen bond, termed chalcogen bond, is defined in this article. By selecting the complexes H(2)CS...Cl(-), F(2)CS...Cl(-), OCS...Cl(-), and SCS...Cl(-) as models, the bond-length change, interaction energy, topological property of the electron charge density and its Laplacian, and the charge transfer of the chalcogen bond ...

Halogen Bond Catalyzed Bromocarbocyclization
Angewandte Chemie International Edition, 2018AbstractA halogen bond catalyzed bromo‐carbocyclization of N‐cinnamyl sulfonamides and O‐cinnamyl phenyl ethers has been developed. N‐methyl 4‐iodopyridinium triflate is used as the halogen‐bonding organocatalyst and the reaction is highly chemoselective.

Halogen Bonding in a Crystalline Sponge
Inorganic Chemistry, 2019Host-guest interactions are the key to the supramolecular chemistry and the further application of the receptors to study the structural details of the small guest molecules. Crystalline sponges as a kind of supramolecular receptor need to be investigated in terms of the binding ability with the guests.

Faraday Discuss., 2017
The models behind simple bonding theory and the origins of some components often proposed to be involved in weak intermolecular bonds are described with special reference to σ-hole bonding, of which halogen bonds are a subset. A protocol for the analysis of weak intermolecular interactions is proposed on the basis of sound physical principles.
