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.

Because of its expected applicability for modulation of molecular recognition phenomena in chemistry and biology, halogen bonding has lately attracted rapidly increasing interest. As most of these processes proceed in solution, the understanding of the influence of solvents on the interaction is of utmost importance.

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 ...

Halogen Bonding in Supramolecular Chemistry
Angewandte Chemie International Edition, 2008AbstractHalogen bonding is the noncovalent interaction where halogen atoms function as electrophilic species. The energetic and geometrical features of the interaction are described along with the atomic characteristics that confer molecules with the specific ability to interact through this interaction.

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.
