Novel bistriazolo[1,3,6]thiadiazepine derivatives have been prepared by the base-catalyzed condensation of aromatic and aliphatic 1,2-diamines with 5-chloro-1,2,3-thiadiazoles, via a multistep process which is thought to involve two Dimroth rearrangements and subsequent loss of hydrogen sulfide by intramolecular nucleophilic substitution.

生物是通过芳香族和脂肪族1,2-二胺与
5-氯-1,2,3-噻二唑的碱催化缩合制备的,该多步过程被认为是涉及两次 Dimroth 重排以及随后通过分子内亲核取代失去
