The preparation of three tris(pyrazolyl)toluidines from trifluoromethylaniline reagents is described that likely takes advantage of (quinoidal) resonance-stabilized activation of the C-F bonds. Subsequent transformations lead to two additional (for a total of five new) tris(pyrazolyl)methylaryls. This simple reaction is remarkable
