Activation of a Metal-Halogen Bond by Halogen Bonding [PDF]

Angewandte Chemie International Edition, 2020
In recent years, the non-covalent interaction of halogen bonding (XB) has found increasing application in organocatalysis. However, reports of the activation of metal-ligand bonds by XB have so far been limited to a few reactions with elemental iodine or

New Type of Halogen Bond: Multivalent Halogen Interacting with π- and σ-Electrons

Molecules, 2017
MP2/aug-cc-pVTZ calculations were performed for complexes of BrF3 and BrF5 acting as Lewis acids through the bromine centre, with species playing a role of Lewis base: dihydrogen, acetylene, ethylene, and benzene. The molecular hydrogen donates electrons

π covalency in the halogen bond [PDF]

Nature Communications, 2020
Current models of halogen bonding describe the σ-symmetric component of this interaction but do not contemplate the possibility of π-covalency. Here the authors provide experimental and computational evidence of π-covalency in halogen bonds involving ...

Multilevel Hollow‐Structured Particles through Halogen‐Bond Regulated Polymer Assembly under 3D Confinement [PDF]

Advanced Science
Engineering of hollow particles with tunable internal structures often requires complicated processes and/or invasive cleavage. Halogen‐bond driven 3D confined‐assembly of block copolymers has shed light on the engineering of polymer organization along ...

Halogen Bond Asymmetry in Solution [PDF]

Journal of the American Chemical Society, 2018
Halogen bonding is the noncovalent interaction of halogen atoms in which they act as electron acceptors. Whereas three-center hydrogen bond complexes, [D center dot center dot center dot H center dot center dot center dot D](+) where D is an electron ...

Halogen-Bonded Driven Tetra-Substituted Benzene Dimers and Trimers: Potential Hosts for Metal Ions

Sci, 2022
Cyclic dimers and trimers of tetra-substituted benzenes, ((HOOC)2-C6H2-(NHI)2), are selected as convenient model systems for investigating NI…O=C halogen bond strength and cooperativity. The four substituents in benzene are chosen so that two of them act

Intermolecular Halogen Bond Detected in Racemic and Optically Pure N-C Axially Chiral 3-(2-Halophenyl)quinazoline-4-thione Derivatives

Molecules, 2022
The halogen bond has been widely used as an important supramolecular tool in various research areas. However, there are relatively few studies on halogen bonding related to molecular chirality. 3-(2-Halophenyl)quinazoline-4-thione derivatives have stable

The Amine Group as Halogen Bond Acceptor in Cocrystals of Aromatic Diamines and Perfluorinated Iodobenzenes

Crystals, 2021
In order to study the proclivity of primary amine groups to act as halogen bond acceptors, three aromatic diamines (p-phenylenediamine (pphda), benzidine (bnzd) and o-tolidine (otol)) were cocrystallised with three perfluorinated iodobenzenes (1,4 ...

“Anti-Electrostatic” Halogen Bonding [PDF]

Angewandte Chemie International Edition, 2020
Halogen bonding (XB) is often described as being driven predominantly by electrostatics, and thus adducts between anionic XB donors (halogen-based Lewis acids) and anions seem counter­intuitive.
