Reactions of Unsaturated Azides, 8. - Azidobutatriene and Azidobutenynes

When 1-azido-4-chloro-2-butyne (11), obtained from 1,4-dichloro-2-butyne (10), is treated with sodium hydroxide in methanol, 4-ethynyl-1H-1,2,3-triazole (19) is the main product besides the two triazoles 9 and 21.On the way from 11 to 19 and 21 azidobutatriene (14) most probably acts as a short-lived intermediate leading to five-membered heterocyclic compounds as azidoallenes do.In contrast to 14, the azidobutenynes 23 and 27 are relatively stable.They mainly give 2H-azirines (24, 28) on thermolysis and photolysis. - Keywords: Azidobutatriene, ring closure of; Triazole, preparation via azidobutatriene; Azirines
