trifluoromethylate: The beneficial properties imparted by the trifluoromethylation of aromatic compounds continue to drive the discovery of novel reagents and reactions for the late‐stage introduction of such moieties. Highlighted here is the recently discovered Sandmeyer trifluoromethylation approach, which now permits aromatic amines to be substrates in a direct trifluoromethylation strategy.
