Halogen–Halogen Nonbonded Interactions [PDF]
ACS Omega, 2021 Halogen-halogen nonbonded interactions were studied for methyl halides and phenyl halides using both B3LYP and MP2 along with 6-311+G* and aug-cc-pVTZ. With the methyl halides, the linear approach was found to lead to little stabilization, whereas the "90°" approach gave 1-2 kcal/mol. This modest stabilization was due to long-range electron correlation

Activation of a Metal‐Halogen Bond by Halogen Bonding [PDF]
Angewandte Chemie International Edition, 2020 Abstract 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 bromine. Herein, we present the activation of metal‐halogen bonds by two

Type II halogen···halogen contacts are halogen bonds [PDF]
IUCrJ, 2013 Cl/Br/I alternative substitutions in a series of dihalophenols indicate that type I and type II halogen···halogen contacts have different chemical nature. Only the latter ones qualify as true halogen bonds, according to the recent IUPAC definition.

Selective C-H Halogenation of Alkenes and Alkynes Using Flavin-Dependent Halogenases
, 2023 Single component flavin-dependent halogenases (FDHs) possesses both flavin reductase and FDH activity in a single enzyme. We recently reported that the single component FDH AetF catalyzes site-selective bromination and iodination of a variety of aromatic
