A Radical Cascade with Double Intramolecular Hydrogen Atom Transfer for the Generation of Bisfunctionalized Cyclopentanes from Linear Alkynes

open access: yesAngewandte Chemie, Volume 138, Issue 5, 28 January 2026.
A radical cascade process involving the activation of two aliphatic C–H bonds in a series of five elementary steps converts readily available terminal alkynes into functionalized cyclopentylmethyl arylsulfones. The methodology delivers flexible synthetic intermediates and was applied to the preparation of diquinanes and triquinanes possessing a rare ...

Probing a Reactive Alkyne Center Aligned via a Triphenylmethane Tripod on Au(111) for Electric Field‐Induced Chemistry by STM and TERS

open access: yesSmall, Volume 22, Issue 7, 2 February 2026.
Electric‐field‐induced chemistry at solid/vacuum interfaces offers precise control over chemical reactions. In this study, a triphenylmethane‐based tripod with a terminal alkyne is anchored upright on a gold surface. Advanced scanning tunneling microscopy and tip‐enhanced Raman scattering confirm the alignment and stability of the reactive center ...

Ab Initio Molecular Dynamics Study of Quadrupolar Spin Relaxation in an Ionic Liquid

open access: yesJournal of Computational Chemistry, Volume 47, Issue 3, 30 January 2026.
This study presents a methodology for describing the relaxation of nuclear spins (with I > 1/2), applicable to ionic liquids of a general nature. Based on ab initio molecular dynamics, we demonstrate the importance of explicit solvation in calculating the relaxation times of the quadrupolar mechanism.

Thiophene Derivatives as Versatile Precursors for (Hetero)Arene and Natural Product Synthesis

open access: yesAngewandte Chemie International Edition, Volume 65, Issue 5, 28 January 2026.
Hidden but Powerful: Thiophenes and their saturated analogues have been demonstrated to be versatile C4‐building blocks that can be rapidly applied to natural product synthesis and the construction of functionalized (hetero)arenes. This minireview aims to provide a concise overview of the strategies and implementations of these sulfur‐containing ...
