Die Oxidation von Hexathioethanen zu Tetrathioethen‐Radikalkationen

Abstract: The oxidation of hexakis(alky1thio)ethanes (RS),C -C(SR), by AICI,/H2CCI2, NOBF,, or I, yields tetrakis(alky1thio)ethene radical cations (RS),C'~C(SR),. The dark violet tetrahydrotetrathiafulvalenium triiodide 1 . I, (n = 2) has been obtained as acrystalline solid.Other derivatives such as the dibenzotetrathiafulvalene (2) and the quinodimethane (4) radical cations have been characterized by ESR spectroscopy in solution: The coupling constants and the y values reveal that the spin density accumulates preferent… Show more

“…4(a)), and a similar but slightly broader spectrum in a frozen toluene glass (g = 2.0078 ± 0.0002, ∆H p-p = 17.2 G). These data coincide with the EPR-parameters of the 10 ϩ cation generated electrochemically and cooled to 77 K, and are also in close agreement with the EPR parameters in the literature for TTF ϩ (8 ϩ ) 30 and for BEDT-TTF ϩ (9 ϩ ). 31 Irradiation of C 60 in toluene at 77 K by XeCl-laser produced a complex spectrum (Fig.…”
