Facile syntheses of bi-1,2,4-triazoles via hydrazonyl halides
Shawali,Farag,Albar,Dawood
, p. 2761 - 2766 (2007/10/02)
Reaction of oxalodihydrazonyl dihalides 1 with sodium azide afforded the corresponding di-azides 2. Reduction of the latter with LiAlH4 yielded the diamidrazones 4 which react with acyl halides to give the bi-1,2,4-triazoles 5. The latter produ
