T. Courcet et al., BIS(ETHYLENEDITHIO)TETRASELENAFULVALENE - SHORT-CUT SYNTHESIS, X-RAY CRYSTAL-STRUCTURE AND PI-ELECTRON DENSITY DISTRIBUTION, New journal of chemistry, 22(6), 1998, pp. 585-589
A convenient one-step reaction for the preparation of 2,3-dihydro-1,4-
dithiin, 3, involved in the synthesis of the organic donor compound bi
s(ethylenedithio)tetraselenafulvalene (BETS), as well as the crystal s
tructure of this donor as determined by X-ray diffraction, are present
ed. A qualitative insight into the pi-electron density distribution is
also discussed.
