Comparing Homodimer and Homotrimer Noncovalent Complexes Involving Coinage Metals: A Theoretical Perspective

open access: yesChemPhysChem, Volume 27, Issue 19, 14 October 2026.
In this study, the ability of M2 clusters (M = Cu, Ag, and Au) to form noncovalent homodimers/homotrimers has been evaluated at the RI‐PBE0‐D4/def2‐TZVPD level of theory. The results have been complemented with QTAIM, NCIplot, and EDA analyses, which helped to shed light on the physical nature of these unconventional noncovalent contacts. In this study,

Synthesis of S‐Arylthioxanthonium Trifluoromethanesulfonates From Thioxanthones and Diaryliodonium Salts by Copper(II) Catalysis and Application to Aryl–Heteroaryl Bond Formation by Direct LED Irradiation

open access: yesEuropean Journal of Organic Chemistry, Volume 29, Issue 38, 13 October 2026.
A straightforward Cu(II)‐catalyzed synthesis of S‐arylthioxanthonium trifluoromethanesulfonates from readily available thioxanthones and diaryliodonium salts is described. A broad range of salts is obtained in moderate to good yields. It is further demonstrated that S‐arylthioxanthonium trifluoromethanesulfonates act as aryl radical precursors under ...

Mechanistic Diversity in Photoexcited Radical Redox Chemistry: A Critical Evaluation

open access: yesAngewandte Chemie International Edition, Volume 65, Issue 42, 12 October 2026.
Many high‐profile examples of photoredox catalysis are proposed to proceed via excitation of an open‐shell intermediate form of the catalyst. However, there is much debate over whether such mechanisms are realistic and, if so, exactly how they can occur.

Selection and Ranking of E-Learning Websites using MCDM based EDAS Technique

open access: yesInternational Journal of Intelligent Systems and Applications in Engineering
This study assesses and orders E-learning websites using predefined evaluation criteria. Employing MCDM methodology, it ranks these websites based on divergent assessment indices. The task of selecting E-learning platforms is tackled using Weighted-Evaluation based on Distance from Average Solution (W-EDAS), a MCDM algorithm tailored for such ...
