Direct C2–H alkylation of indoles driven by the photochemical activity of halogen-bonded complexes
Beilstein Journal of Organic Chemistry, 2023 A light-driven metal-free protocol for the synthesis of sulfone-containing indoles under mild conditions is reported. Specifically, the process is driven by the photochemical activity of halogen-bonded complexes formed upon complexation of a sacrificial ...

Alternatives to free molecular halogens as chemoselective reactants: Catalysis of organic reactions with reusable complexes of halogen metal salts [PDF]
, 2012 Organometallic complexes of halogen metallic salts have been used as catalysts in different organic reactions, mainly the oxidation of organic compounds. Their use has not only allowed the reduction of the amounts of catalyst (since they can be reused)

Intramolecular halogen–halogen bonds?
Physical Chemistry Chemical Physics, 2013 By analysing the properties of the electron density in the structurally simple perhalogenated ethanes, X3C-CY3 (X, Y = F, Cl), a previously overlooked non-covalent attraction between halogens attached to opposite carbon atoms is found. Quantum chemical calculations extrapolated towards the full solution of the Schrödinger equation reveal the complex ...

Activation of a Metal‐Halogen Bond by Halogen Bonding [PDF]
Angewandte Chemie International Edition, 2020 AbstractIn 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.

Characterization of Double Leached Waelz Oxide for Identification of Fluoride Mineral
Metals, 2019 Double leached Waelz oxide (DLWO), with 76% zinc, is a secondary zinc containing raw materials obtained by the treatment of electric arc furnace dust. The content of fluoride in DLWO is still too high for direct leaching, as fluoride has a detrimental ...
