A Se···O bonding catalysis approach to the synthesis of calix[4]pyrroles

open access: yesBeilstein Journal of Organic Chemistry, 2022
Described herein is a chalcogen bonding catalysis approach to the synthesis of calix[4]pyrrole derivatives. The Se···O bonding interactions between selenide catalysts and ketones gave rise to the catalytic activity in the condensation reactions between ...

Supramolecular rectangles through directional chalcogen bonding [PDF]

open access: yesChemical Communications, 2021
Supramolecular rectangles are built from the 2+2 chalcogen bonding-based (ChB) association of 1,8-bis(telluromethylethynyl)-anthracene and linear ditopic Lewis bases.

A Quantitative Molecular Orbital Perspective of the Chalcogen Bond

open access: yesChemistryOpen, 2021
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.

The Balance between Hydrogen Bonds, Halogen Bonds, and Chalcogen Bonds in the Crystal Structures of a Series of 1,3,4-Chalcogenadiazoles

open access: yesMolecules, 2021
In order to explore how specific atom-to-atom replacements change the electrostatic potentials on 1,3,4-chalcogenadiazole derivatives, and to deliberately alter the balance between intermolecular interactions, four target molecules were synthesized and ...

Chalcogen bond-guided conformational isomerization enables catalytic dynamic kinetic resolution of sulfoxides

open access: yesNature Communications, 2022
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 ...

The Relevance of Experimental Charge Density Analysis in Unraveling Noncovalent Interactions in Molecular Crystals

open access: yesMolecules, 2022
The work carried out by our research group over the last couple of decades in the context of quantitative crystal engineering involves the analysis of intermolecular interactions such as carbon (tetrel) bonding, pnicogen bonding, chalcogen bonding, and ...

Selenoxides as Excellent Chalcogen Bond Donors: Effect of Metal Coordination

open access: yesMolecules, 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.
