A General Hydrotrifluoromethylation of Unactivated Olefins Enabled by Voltage‐Gated Electrosynthesis
Angewandte Chemie, Volume 137, Issue 4, January 21, 2025.This work presents the discovery and development of a regioselective hydrotrifluoromethylation of olefins under electrochemical conditions. Guided by mechanistic studies, a voltage‐gated electrolysis was designed by integrating two redox processes operating within a narrow potential window.

Ball‐Milling Assisted Iron‐Catalyzed Difluoromethylation Toward the Synthesis of Valuable Oxindoles
ChemSusChem, Volume 18, Issue 24, December 13, 2025.An iron‐catalyzed difluoroalkylation of acrylamides under ball‐milling conditions affords oxindoles in up to 85% yield. Analytical studies reveal that the apparent piezoelectric activity originates from iron leaching caused by milling assembly abrasion during the reaction process. The iron‐catalyzed process proves to be efficient with a broad substrate

Helvetica Chimica Acta, Volume 108, Issue 12, December 2025.Sodium ascorbate is a safe and sustainable electron donor, yet its use in solution‐state photocatalysis reactions is often limited by its poor solubility in organic solvents. In this study, typical electron donors used for net reductive pinacol coupling reactions, such as DIPEA and the Hantzsch ester, are replaced with the more benign sodium ascorbate,
