Catalytic Antioxidant Activity of Acyclic and Macrocyclic Selenides: Insights Into Structure–Activity Relationships and Mechanisms From Kinetic and Computational Studies

European Journal of Organic Chemistry, EarlyView.
Structure–activity relationships of antioxidant activities of selenides were established by experimental and computational methods. Several structures displayed strong catalytic activity in an NMR‐based assay. Diverse selenides were shown to act as potent catalytic antioxidants.

Homoleptic Bismuth Alkynes: Isolable Reagents for Selective Alkynyl Radical Transfer

Angewandte Chemie, Volume 138, Issue 4, 22 January 2026.
The first series of fully characterized homoleptic alkynyl bismuth compounds Bi(C≡CR)3 is presented. Facile homolytic Bi–C bond cleavage grants access to alkynyl radicals, which have been employed in selective C–X bond formation (X = C, B, Se, Te). This complements existing strategies for alkynyl radical generation as it proceeds under mild and purely ...

A Para‐Selective Kolbe–Schmitt Reaction

Angewandte Chemie, Volume 138, Issue 4, 22 January 2026.
Discovered over 150 years ago, the Kolbe–Schmitt carboxylation has established itself as one of the most well‐known chemical reactions. However, the process often requires extreme pressures and high temperatures. Here, we present a unique para‐selective Kolbe–Schmitt‐type carboxylation that proceeds at relatively low temperatures and uses near ...

Reversible Dihydrogen Splitting and Diradical Reactivity of 1,4‐Digermabenzene‐1,4‐diide

ChemistryEurope, Volume 4, Issue 5, May 2026.
The diradical reactivity of the 1,4‐digermabenzene‐1,4‐diide, [(ADC)Ge]2, has been demonstrated with a range of substrates. Notably, it undergoes reversible dihydrogen splitting and radical coupling with TEMPO (2,2,6,6‐tetramethylpiperidinyloxyl = RO), forming [(ADC)GeH]2 and [(ADC)Ge(OR)]2, respectively.

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.
