Abstract
Abstract 2,3-Bis(bromomethyl)TTFs 4 are used as precursors of 2,3-dimethylene-[2H]-TTFs 5 to reach cycloadducts of high synthetic interest via a [4+2] cycloaddition with quinonic derivatives. Subsequent Horner-Wadsworth-Emmons olefinations with a 1,3-dithiole phosphonate anion afforded highly extended and sulfur-rich analogs of tetrathiafulvalene 1.
