Abstract
Cyclic sulfate ester 6 reacts readily with dithiolate 4 to give meso a nd dl cyclic products 8 and 9. The crystal structure of 9 shows two sh ort S...S intermolecular interactions (< 3.4 Angstrom) between trithio carbonate groups, due to cooperative polarisations and the highly asym metric shape of the bonded S atom. The latter effect is mainly respons ible for the 'short' S...S contacts in ET's radical cation salts. In c ontrast to similar systems, the sp(3) C atoms of the six-membered ring in 9 are displaced to the same side of the dithiole plane.
