| Abstract: | First evidence for the existence of free trifluoromethyl anion CF3− has been obtained. The 3D‐caged potassium cation in K(crypt‐222)]+ is inaccessible to CF3−, thus rendering it uncoordinated (“naked”). Ionic K(crypt‐222)]+ CF3− has been characterized by single‐crystal X‐ray diffraction, solution NMR spectroscopy, DFT calculations, and reactivity toward electrophiles. |
