Convenient synthesis of bis(benzo)-fused BEDT-TTF and higher homologues: new electron donor molecules for organic charge transfer salts and 'molecular rulers'

摘要

A convenient synthesis of bis(benzo)- and bis(naphtho)-fused bis(ethylenedithio) tetrathiafulvalene (BEDT-TTF or ET) derivatives, employing the (4+2) cycloaddition reaction of oligo(1,3-dithiole-2,4, 5-trithione) with appropriate alkenes as a key step, is presented.
