p-Benzoquinone derivatives fused with sulphur-containing heterocycles are strong electronacceptors and some of their charge transfer complexes with electrondonors show high electrical conductivities.

Benzocyclohexa-2,5-diene-1,4-dione-1,3-thiole-2-thione (2) was synthesized starting with 2,3-dichloronapthoquinone (1). Compounds 3 and 4 were also obtained; however, the yield of 2 can be increased through control of the temperature and reaction time. Reaction of 2 with triethylphosphite gave 5 and the tetrathiafulvalene ester 6. The tetrathiafulvalenequinone (9) was obtained by hydrolysis of 6 followed by oxidation of & Compound 9 was obtained more directly by hydrogenation of 2 followed by coupling with triethylphosphite and oxidation. Chloranil was used to prepare the dithiafulvene quinone 12 which was reduced, coupled with triethylphosphite to form, presumably, polymer 13. The reactions were repeated using the hexanoic acid esters of the corresponding hydroquinone thiafulvalenes. The crystal structures of 2, 3, 4, 5, 6a and 10 were determined by X-ray diffraction. Cyclic voltammetry studies show the tetrathiafulvalene quinones reduce like quinones, but do not exhibit the oxidation properties of tetrathiafulvalenes.

An Anion Radical Salt of a Quinone Fused with 1,3-Dithiole Units. Crystal and Molecular Structure of a Tetraethylammonium Salt of 2,6-Dithioxobenzo[1,2-<i>d</i>:4,5-<i>d</i>′]bis[1,3]dithiole-4,8-dione
Crystal structure of the title salt was determined by the X-ray analysis. Segregated columnar stacks of anionradicals are formed along the c axis, in which quinone molecules are not spaced equally but forming dyads with short contacts between sulfur atoms.
