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 products were alternatively prepared by reaction of 2 with triphenylphosphine to give the phosphinimines 6 followed by treatment of the latter with acyl halides.
草酰二肼基二卤化物1与叠氮化钠反应,得到相应的二叠氮化物2。后者与的LiAlH的还原4,得到diamidrazones 4,其与酰卤反应,得到双-1,2,4-三唑5。或者,通过2与三苯基膦反应得到膦亚胺6,然后用酰基卤处理后者来制备后者的产物。
