Both of the newly synthesized 2 and (EDT-TTF) exhibit metallic behaviour around room temperature at ambient pressure; tight-binding band calculation indicates that the former has a nearly three-dimensional Fermi surface owi

The title Wittig reagent 5 has been prepared in three steps (84percent overall yield) from 4,5-bis(benzoylthio)-1,3-dithiole-2-thione.Reactions of ylide 7, generated by treatment of 5 with diisopropylethylamine at room temperature, have been exploited in the synthesis of new unsymmetrical tetrathiafulvalenes and 1,3-dithiol-2-ylidene derivatives.Subsequent removal of the benzoyl protecting group with sodium ethoxide liberates the transient TTF-dithiolate or 1,3-dithiole-dithiolate anions which can be alkylated in situ.The X-ray crystal structures of compounds 17 and 18 are reported: close nonbonded S...O intramolecular interactions are observed in both structures.
