Isolation and characterization of a non-rigid hexamethylbenzene-SO2+ complex

Moritz Malischewski, Konrad Seppelt
During our preparation of the pentagonal-pyramidal hexamethylbenzene-dication C₆(CH₃)₆²+ we isolated the unprecedented dicationic species C₆(CH₃)₆SO²+ (AsF₆-)₂ from the reaction of hexamethylbenzene with a mixture of anhydrous HF, AsF₅ and liquid SO₂. This compound can be understood as a complex of unknown SO²+ with hexamethylbenzene. Herein, we report the synthesis, its molecular structure and its spectroscopic characterization.
