EVALUATIONS CONCERNING THE HALOGEN BOND AND HYDROGEN BOND RELATIONSHIP [PDF]

, 2020
The chemical advances of this century are likely to be driven by the ability to predict and control noncovalent interactions. While the hydrogen bond continues to captivate the interests of scientists, the development of non-traditional noncovalent ...

Halogen Bond Asymmetry in Solution

, 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 ...

Extended Assemblies of Ru(bpy)(CO)₂X₂ (X = Cl, Br, I) Molecules Linked by 1,4-Diiodotetrafluoro-Benzene (DITFB) Halogen Bond Donors

Crystals, 2019
The ruthenium carbonyl compounds, Ru(bpy)(CO)2X2 (X = Cl, Br or I) act as neutral halogen bond (XB) acceptors when co-crystallized with 1,4-diiodotetrafluoro-benzene (DITFB).

Bidentate chiral bis(imidazolium)‐based halogen‐bond donors

, 2020
Even though halogen bonding — the noncovalent interaction between electrophilic halogen substituents and Lewis bases — has now been established in molecular recognition and catalysis, its use in enantioselective processes is still very rarely explored ...

EXPLORING THE HALOGEN BOND THROUGH ANION RECOGNITION, THE HYDROGEN BOND ENHANCED HALOGEN BOND, AND ORGANOCATALYSIS

, 2019
Natural and synthetic molecules employ noncovalent interactions to engender molecular form and function. The halogen bond is a recently rediscovered noncovalent interaction that has proven advantageous in the solution, solid and gas phases.

The diiodomethyl-sulfonyl moiety: an unexplored halogen bond-donor motif

, 2019
Herein, we report the crystal structures of the antimicrobial agent diiodomethyl-p-tolylsulfone and of three halogen bonded co-crystals demonstrating that the bioactive moiety -SO2CHI2 can function as a quite effective halogen bond based motif in the ...
