Chalcogen‐Bonding Catalysis with Telluronium Cations [PDF]
Angewandte Chemie, 2021 AbstractChalcogen bonding results from non‐covalent interactions occurring between electrodeficient chalcogen atoms and Lewis bases. Among the chalcogens, tellurium is the strongest Lewis acid, but Te‐based compounds are scarcely used as organocatalysts.

Halogen bonding and chalcogen bonding mediated sensing
Chemical Science, 2022 Sigma–hole mediated detection of anions is rapidly emerging as a new paradigm in supramolecular sensor chemistry. Herein, we provide an overview of this field including halogen bonding and chalcogen bonding optical, electrochemical and other sensors.

Assessing the Possibility and Properties of Types I and II Chalcogen Bonds
Crystals, 2023 Type I and II halogen bonds are well-recognized motifs that commonly occur within crystals. Quantum calculations are applied to examine whether such geometries might occur in their closely related chalcogen bond cousins. Homodimers are constructed of the

Chalcogen Bond Involving Zinc(II)/Cadmium(II) Carbonate and Its Enhancement by Spodium Bond
Molecules, 2021 Carbonate MCO3 (M = Zn, Cd) can act as both Lewis acid and base to engage in a spodium bond with nitrogen-containing bases (HCN, NHCH2, and NH3) and a chalcogen bond with SeHX (X = F, Cl, OH, OCH3, NH2, and NHCH3), respectively.

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,

Activating Chalcogen Bonding (ChB) in Alkylseleno/Alkyltelluroacetylenes toward Chalcogen Bonding Directionality Control [PDF]
Angewandte Chemie International Edition, 2020 AbstractActivation of a deep electron‐deficient area on chalcogen atoms (Ch=Se, Te) is demonstrated in alkynyl chalcogen derivatives, in the prolongation of the (C≡)C−Ch bond. The solid‐state structures of 1,4‐bis(methylselenoethynyl)perfluorobenzene (1Se) show the formation of recurrent chalcogen‐bonded (ChB) motifs.

Pseudo-Bifurcated Chalcogen Bond in Crystal Engineering
Crystals, 2018 The concept of pseudo-bifurcated chalcogen bond has been proposed for the first time in this paper. It was found that the anticooperative effects between two chalcogen bonds of the pseudo-bifurcated chalcogen bond are not very large as compared to those ...
