Special Solvation Behaviour of Salts in Ionic Liquid
, 2012 In a previous study1 from the Welton Group, the reactivity resulting from mixing two different and reactive salts together was observed to be highly dependent on the type of solvent, with molecular and ionic liquids exhibiting fundamentally different ...

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.
