WebA straightforward synthetic entry to the principal classes of electrophilic trifluoromethylthiolating agents is presented. It draws on inexpensive, shelf-stable tetramethylammonium trifluoromethylthiolate (Me4N–SCF3) as the SCF3source in the place of stoichiometric coinage metal-SCF3complexes. (Figure presented.). WebUsing experimental reactivity tests, ReactIR and computational techniques, it is showcased that the solid (Me4 N)SCF3 functions as a safe reservoir for S=CF2, allowing large-scale and late-stage synthetic applications without special reaction control. While thiophosgene finds widespread usage on a multi-ton scale, its fluorinated counterpart S=CF2 is …
