A facile preparation of tetrathiafulvalenes having alkylthio groups from 1,3-dithiole-2-thiones using a high-pressure reaction
Abstract
Tetrathiafulvalenes such as bis(ethylenedithio)tetrathiafulvalene (BEDT-TTF) having alkylthio substituents have been prepared in good yields by direct desulphurization of 1,3-dithiole-2-thiones with trimethyl phosphite under high pressure.
