Abstract

SNSMF₆ (M = As, Sb) reacts with 1,4-benzoquinone in a series of cycloaddition and oxidative dehydrogenation reactions to give 3 (MF₆)₂ which on reduction with CsI yields the unique semiquinodal–thiazyl radical-cation (3⁺+˙) as observed by X-band solution ESR and supported by DFT calculations.
