Azulenopentathiepin was prepared by the reaction of azulene with elemental sulfur in boiling pyridine. Bis(thiolate) generated from the pentathiepin reacted with electrophiles such as iodomethane, methyl chloroformate, N,N%26apos;-carbonyldiimidazole and N,N%26apos;-thiocarbonyldiimidazole to afford the corresponding azulene derivatives. Desulfuration of the pentathiepin and the successive reaction with DMAD or a Pd(0) reagent afforded a 1,4-dithiin compound or Pd complexes.
