Resonant X‐Ray Diffraction of Conjugated Polymers at the Selenium K‐Edge

Macromolecular Rapid Communications, Volume 47, Issue 9, 5 May 2026.
Analogous to isomorphous replacement used in X‐ray crystallography studies of proteins, substituting sulfur for selenium in conjugated polymers enables resonant diffraction studies of molecular packing down to the length scale of π‐‐π stacking. Two selenium‐containing polymers are studied with a comparison made between sulfur K‐edge and selenium K‐edge

Addition Reactions of Phosphorus‐Centered Radicals Onto Olefins: Interplay Between Stability and Reactivity

Chemistry – A European Journal, Volume 32, Issue 16, 25 April 2026.
The energetics of the addition reaction of P‐centered radicals onto alkenes are primarily ruled by the stability of the attacking radical, as outlined by the computational screening of a wide range of reactions. In addition, donor‐acceptor substituents at the olefin have an important tuning role.

Synthesis and crystal structure of the adduct between 2-pyridylselenyl chloride and isobutyronitrile

Acta Crystallographica Section E: Crystallographic Communications
The reaction between 2-pyridylselenenyl chloride and isobutyronitrile results in the formation of the corresponding cationic pyridinium-fused 1,2,4-selenodiazole, namely, 3-(propan-2-yl)-1,2,4-[1,2,4]selenadiazolo[4,5-a]pyridin-4-ylium chloride ...

Electrochemical Regioselective Chalcogenocyclizations of 2‐Alkynylbenzamides in Flow

ChemElectroChem, Volume 13, Issue 8, 15 April 2026.
A sustainable electrochemical method enables regioselective 6‐endo‐dig chalcogeno‐cyclizations of ortho‐alkynylbenzamides in continuous flow. Using diphenyl diselenide as an electroactive coupling partner, the process avoids metals and stoichiometric oxidants, offering scalable access to selenium‐containing heterocycles.

Metalloids: Semi as Metals yet Full of Antimicrobial Potential

ChemMedChem, Volume 21, Issue 7, 14 April 2026.
Metalloids such as boron (B), silicon (Si), germanium (Ge), arsenic (As), antimony (Sb), and tellurium (Te) bridge metals and non‐metals, displaying unique chemical versatility. Recent research highlights their diverse antimicrobial and therapeutic potentials, from natural products to synthetic organic and organometallic molcules, underscoring renewed ...

Unveiling σ- and π-hole interactions in COSe-XCN (X = F, Cl, Br, and I): Theoretical insights into halogen substitution effects

Results in Chemistry
XCN molecules (X = F, Cl, Br, I) are linear pseudohalogen species containing a reactive and toxic cyanide group. Their high electrophilicity and toxicity limit experimental studies.
