18F‐Radiopharmaceutical Diversification Enabled by Deaminative Cross‐Electrophile Couplings
Angewandte Chemie, Volume 138, Issue 4, 22 January 2026.A general Ni‐mediated (C)sp2–(C)sp3 cross‐coupling expedites access to 18F‐radiopharmaceuticals, essential for positron emission tomography imaging and drug discovery. This late‐stage diversification approach was implemented across three user‐friendly automated protocols affording 18F‐radiotracers in sufficient quantities for imaging.

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
