The Origin of Chalcogen-Bonding Interactions [PDF]
Journal of the American Chemical Society, 2017 Favorable molecular interactions between group 16 elements have been implicated in catalysis, biological processes, and materials and medicinal chemistry. Such interactions have since become known as chalcogen bonds by analogy to hydrogen and halogen bonds. Although the prevalence and applications of chalcogen-bonding interactions continues to develop,

Selenoxides as Excellent Chalcogen Bond Donors: Effect of Metal Coordination
Molecules, 2022 The chalcogen bond has been recently defined by the IUPAC as the attractive noncovalent interaction between any element of group 16 acting as an electrophile and any atom (or group of atoms) acting as a nucleophile.

Nature and strength of chalcogen–π bonds [PDF]
Physical Chemistry Chemical Physics, 2018 We have analyzed the chalcogen–π bonding mechanism in a systematic series of model systems through Kohn–Sham molecular orbital theory and a quantitative energy decomposition scheme.

Catalysis with Chalcogen Bonds
Angewandte Chemie International Edition, 2016 AbstractHerein, we introduce catalysts that operate with chalcogen bonds. Compared to conventional hydrogen bonds, chalcogen bonds are similar in strength but more directional and hydrophobic, thus ideal for precision catalysis in apolar solvents. For the transfer hydrogenation of quinolines and imines, rate enhancements well beyond a factor of 1000 ...

Chalcogen–chalcogen secondary bonding interactions in trichalcogenaferrocenophanes
CrystEngComm, 2016 The solid-state structures of all members in the series of trichalcogenaferrocenophanes [FeIJC5H4E)2E′] (E, E′ = S, Se, Te) (1–9) have been explored to understand the trends in secondary bonding interactions (SBIs) between chalcogen elements sulfur, selenium, and tellurium.

A Structural and Spectroscopic Study of the First Uranyl Selenocyanate, [Et4N]3[UO2(NCSe)5]
Inorganics, 2016 The first example of a uranyl selenocyanate compound is reported. The compound [Et4N]3[UO2(NCSe)5] has been synthesized and fully characterized by vibrational and multinuclear (1H, 13C{1H} and 77Se{1H}) NMR spectroscopy. The photophysical properties have

A Combined Halogen‐ and Chalcogen‐Bonding Organocatalyst
Advanced Synthesis & Catalysis, 2023 AbstractApplications of both halogen and chalcogen bonding in organocatalysis are by now well established with various examples. However, the combination of both interactions within one catalyst is currently unknown. Herein, we describe the synthesis of such a mixed chalcogen‐ and halogen‐bond donor and present a first indication of its catalytic ...
