Does Oxygen Feature Chalcogen Bonding? [PDF]
Molecules, 2019 Using the second-order Møller−Plesset perturbation theory (MP2), together with Dunning’s all-electron correlation consistent basis set aug-cc-pVTZ, we show that the covalently bound oxygen atom present in a series of 21 prototypical ...

Halogen bonding and chalcogen bonding mediated sensing. [PDF]
Chem Sci, 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.

Selection of isomerization pathways of multistep photoswitches by chalcogen bonding [PDF]
Nature Communications, 2023 Multistep photoswitches are able to engage in different photoisomerization pathways and are challenging to control. Here we demonstrate a multistep sequence of E/Z isomerization and photocyclization/cycloreversion of photoswitches via manipulating the ...

Cooperative chalcogen bonding interactions in confined sites activate aziridines [PDF]
Nature Communications, 2022 The activation of aziridines is typically achieved via reaction with strong Lewis acids or transition metals. Here, the authors report that cooperative Se ∙ ∙∙O and Se ∙ ∙∙N noncovalent interactions can activate sulfonyl-protected aziridines, which ...

Supramolecular catalysis with ethers enabled by dual chalcogen bonding activation [PDF]
Nature Communications, 2023 The activation of ethers by weak interactions is a long-standing objective in supramolecular catalysis, but yet it remains an underdeveloped topic. The obstacles towards solving this problem are prominent since it is difficult for a weak interaction to ...

Methyl Scanning for Mechanochemical Chalcogen‐Bonding Cascade Switches [PDF]
ChemistryOpen, 2020 Chalcogen‐bonding cascade switching was introduced recently to produce the chemistry tools needed to image physical forces in biological systems. In the original flipper probe, one methyl group appeared to possibly interfere with the cascade switch.

Polymorphism, Halogen Bonding, and Chalcogen Bonding in the Diiodine Adducts of 1,3- and 1,4-Dithiane [PDF]
Molecules, 2021 Through variations in reaction solvent and stoichiometry, a series of S-diiodine adducts of 1,3- and 1,4-dithiane were isolated by direct reaction of the dithianes with molecular diiodine in solution.

Selenium(IV) Polybromide Complexes: Structural Diversity Driven by Halogen and Chalcogen Bonding [PDF]
Molecules, 2022 Reactions between bromoselenate(IV)-containing solutions, dibromine and salts of pyridinium-family organic cations resulted in structurally diverse, bromine-rich polybromine-bromoselenates(IV): (4-MePyH)5[Se2Br9][SeBr6](Br3)2 (1), (2-MePyH)2{[SeBr6](Br2)}

Chalcogen bonding in the solid-state structures of 1,3-bis(benzimidazoliumyl)benzene-based chalcogen-bonding donors. [PDF]
Acta Crystallogr C Struct Chem, 2023 1,3-Bis(benzimidazoliumyl)benzene-based chalcogen-bonding catalysts were previously successfully applied in different benchmark reactions. In one of those examples, i.e. the activation of quinolines, sulfur- and selenium-based chalcogen-bonding catalysts showed comparable properties, which is unexpected, as the selenium-containing catalysts should show

Chalcogen Bonding in Co-Crystals: Activation through 1,4-Perfluorophenylene vs. 4,4′-Perfluorobiphenylene Cores [PDF]
Molecules, 2021 The ability of alkylseleno/alkyltelluroacetylenes such as bis(selenomethylethynyl)-perfluorobenzene (4F-Se) to act as a ditopic chalcogen bond (ChB) donor in co-crystals with ditopic Lewis bases such as 4,4′-bipyridine is extended here to the ...
