Selenoxides as Excellent Chalcogen Bond Donors: Effect of Metal Coordination [PDF]
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.

A Quantitative Molecular Orbital Perspective of the Chalcogen Bond [PDF]
We have quantum chemically analyzed the structure and stability of archetypal chalcogen‐bonded model complexes D2Ch⋅⋅⋅A− (Ch = O, S, Se, Te; D, A = F, Cl, Br) using relativistic density functional theory at ZORA‐M06/QZ4P.

Chalcogen Bond Involving Zinc(II)/Cadmium(II) Carbonate and Its Enhancement by Spodium Bond [PDF]
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.

Chalcogen bond-guided conformational isomerization enables catalytic dynamic kinetic resolution of sulfoxides [PDF]
Conformational isomerization of organic molecules can be guided by noncovalent interactions. Here, the authors report the synthesis of chiral sulfoxides catalyzed by N-heterocyclic carbenes; intramolecular chalcogen bonding interactions are key for ...

Pseudo-Bifurcated Chalcogen Bond in Crystal Engineering
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 ...

A Robust Supramolecular Heterosynthon Assembled by a Hydrogen Bond and a Chalcogen Bond
The 1:1 and 2:1 cocrystals of isophthalic acid and 2,1,3-benzoselenadiazole have been successfully synthesized and resolved; the noncovalent interactions in the crystal structures have been studied in detail by quantum chemical calculations.

Carbon–Halogen Bond Activation by Selenium‐Based Chalcogen Bonding [PDF]
AbstractChalcogen bonding is a little explored noncovalent interaction similar to halogen bonding. This manuscript describes the first application of selenium‐based chalcogen bond donors as Lewis acids in organic synthesis. To this end, the solvolysis of benzhydryl bromide served as a halide abstraction benchmark reaction.

Activation of the Disulfide Bond and Chalcogen–Chalcogen Interactions: An Experimental (FTICR) and Computational Study [PDF]
AbstractDimethyldisulfide (I) is the simplest model of the biologically relevant family of disubstituted disulfides. The experimental study of its gas‐phase protonation has provided, we believe for the first time, a precise value of its gas‐phase basicity. This value agrees within 1 kJ mol−1 with the results of G3 calculations.
