Abstract

Triethyloxonium hexachloroantimonate [Et₃O⁺SbCl₆^-] is a selective oxidant of aromatic donors (ArH), and it allows the facile preparation and isolation of crystalline paramagnetic salts [ArH^+•, SbCl₆^-] for the X-ray structure determination of various aromatic cation radicals. The mechanistic relationship between the Meerwein salt [Et₃O⁺SbCl₆^-] and the pure Lewis acid oxidant SbCl₅ is based on a prior ethyl transfer from oxygen to chlorine within the ion pair.
