Selective C-H Halogenation of Alkenes and Alkynes Using Flavin-Dependent Halogenases [PDF]
, 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

3-Selective Halogenation of Pyridines via Zincke Imine Intermediates [PDF]
, 2022 Pyridine halogenation reactions are crucial for obtaining the vast array of derivatives required for drug and agrochemical development. Yet, despite more than a century of synthetic endeavors, there are no broadly applicable 3-selective halogenation ...

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

Decarboxylative Halogenation of Indoles by Vanadium Haloperoxidases [PDF]
, 2023 Halogenated heteroarenes are key building blocks across numerous chemical industries. Here, we report that vanadium haloperoxidases are capable of producing 3-haloindoles through decarboxylative halogenation of 3-carboxyindoles.

Introducing N-X Anomeric Amides: Powerful Electrophilic Halogenation Reagents [PDF]
, 2023 Electrophilic halogenation is a widely-used tool employed by medicinal chemists to either pre-functionalize molecules for further diversity or incorporate a halogen atom in drugs or drug-like compounds to solve metabolic problems or modulate off-target ...

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.

Role of a secondary coordination sphere residue in halogenation catalysis of non-heme iron enzymes [PDF]
, 2022 Chemo- and regio-selective catalysis of C(sp3)-H halogenation reaction is a formidable goal in chemical synthesis. 2-oxo-glutarate (2OG) dependent non-heme iron halogenases catalyze selective chlorination/bromination of C-H bonds and exhibit high ...
