Six-Membered Rings With Two or More Heteroatoms With at Least One Selenium or Tellurium

Reaction of tetracyanoethylene with diselenium dichloride: a route to pyrrolo[2,3-c][1,2,6]selenadiazines

“…14 Higher nitrogen containing selenazoles, 15 in particular 1,2,5-selenodiazoles, are of interest as components of conducting materials, e.g., 4,7-di(selenophen-2yl)benzo[c][1,2,5]selenadiazole (3) can be electrochemically polymerised to afford a low band gap (1.45 eV) conducting polymer. 16 Six-membered selenadiazines 17 are by comparison rare. To the best of our knowledge, only three 1,2,6-selenadiazine containing polycyclic ring systems have been reported.…”
