Frontiers in Chemistry, 2020 The pnicogen, chalcogen, and halogen bonds between 6-OXF2-fulvene (X = As, Sb, Se, Te, Br, and I) and three nitrogen-containing bases (FCN, HCN, and NH3) are compared.

Halogen Bonding: An Odd Chemistry? [PDF]
The Chemical Record, 2021 AbstractHalogen bonding is a flourishing field of research, but has for long been little recognized. The same goes for its scientific hero, Odd Hassel, who laid the foundations for all current developments. The crystallographic observation of halogen−oxygen interatomic distances shorter than the sum of the van der Waals radii of the involved atoms, and

Astatine Facing Janus: Halogen Bonding vs. Charge-Shift Bonding
Molecules, 2021 The nature of halogen-bond interactions was scrutinized from the perspective of astatine, potentially the strongest halogen-bond donor atom. In addition to its remarkable electronic properties (e.g., its higher aromaticity compared to benzene), C6At6 can

Crystals, 2017 Seventeen new halogen-bonded co-crystals characterized by single crystal X-ray analysis are presented from 8 × 4 combinations using methyl-substituted pyridine N-oxides and 1,ω-diiodoperfluoroalkanes. The N−O group in six of 17 co-crystals is monodentate

Halogen Bonding in Crystal Engineering [PDF]
Acta Crystallographica Section A Foundations of Crystallography, 2005 The term halogen bonding encompasses any non-covalent interaction involving halogens as electrophilic species. High strength and directionality are the remarkable features of halogen bonding that fully justify its use as a primary intermolecular interaction to dictate molecular self-assembly processes.

Transmembrane Halogen-Bonding Cascades
Journal 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

Halogen Bonding in Two‐Dimensional Crystal Engineering
ChemistryOpen, 2020 Halogen bonds, which provide an intermolecular interaction with moderate strength and high directionality, have emerged as a promising tool in the repertoire of non‐covalent interactions.

In silico and in vitro exploration of a tyrosinase for biocatalytic production of catechols
FEBS Open Bio, EarlyView.Tyrosinase from Ralstonia pseudosolanacearum is a promising biocatalyst for producing valuable catechols from monophenol substrates. This tyrosinase is uniquely suited to this due to its high monophenolase : diphenolase ratio. We combined in silico docking and in vivo kinetic characterisation of this tyrosinase with 11 industrially relevant monophenols,

Bulletin of the Chemical Society of Ethiopia, 2017 The theoretical calculations of the complexes formed by pyrazine (PZ) with hypohalous acids (HOX; X= F, Cl, Br and I) have been carried out at the MP2/6-311++G(2d,2p) computational level.

Advanced Engineering Materials, EarlyView.Solvate ionic liquids lubrication reduced the coefficient of friction by ∼60% compared to dry sliding, reaching steady‐state values as low as 0.04–0.05. Corrosion weight‐loss measurements in 1 M HCl further demonstrated significant inhibition behavior, with only 100 ppm of [Li(G3)][TFSI] (∼68.5 μL/L) reducing corrosion‐product weight loss by 63 ...
