Aryl and Alkyl Radiotrifluoromethylation via Metallaphotoredox‐Mediated Radical Cross‐Coupling

Angewandte Chemie, Volume 138, Issue 16, 13 April 2026.
The metallaphotoredox‐mediated radiotrifluoromethylation of arenes and alkanes is described. The operationally simple protocols make use of substrates bearing thianthrenium salts (TT) or N‐hydroxyphthalimide (NHPI) esters and CF218FI. The reaction proceeds through a Ru‐mediated radical formation followed by a Cu‐mediated radical cross‐coupling step and

Generation of a Ground‐State Electron Donor Utilizing Stored Light Energy

Chemistry – A European Journal, EarlyView.
Chemically stored light energy enables the generation of dianion reductants (∼−2.7 V) from vicinal diols derived from diaryl ketone photodimerization. These ground‐state electron donors efficiently reduce challenging substrates at room temperature, including aryl bromides, alkyl iodides, and sulfonamides.
