Tetrathiafulvalenes, ?-Donors, Organic ConductorsStarting from 1,3-dithiolodithiin-2-thione, the title thione was prepared by a fourstep sequence (lithiation with lithium diisopropylamide, addition of Se, treatment with ZnCl2 in the presence of n-Bu4NBr, and alkylation with 1,2-dibromoethane).Self-coupling as well as cross-coupling with similar compounds via triethyl phosphite afforded new tetrathiafulvalenes, precursors of conducting salts.
