Abstract The direct ortho ‐trifluoromethylation of arenes, including heteroarenes, with TMSCF 3 has been accomplished by a copper(II)‐promoted CH activation reaction which completes within 30 minutes. Mechanistic investigations are consistent with the involvement of CH activation, rather than a simple electrophilic aromatic substitution (S E Ar), as the key step.
