Substituted pyrimidine, 1,2,4-triazole and 1,2,4-oxadiazole have been synthesized from various tertiary amides.The secondary amides give 1,3,5-triazinium perchlorates via, in most cases isolable acyclic triazahexadienylium intermediates.
REACTION OF 3-AZIDO-5-PHENYL-1,2,4-OXADIAZOLE WITH DIMETHYLFORMAMIDE, A NEW DEOXYGENATIVE COUPLING REACTION

When 3-bromo-5-phenyl-1,2,4-oxadiazole is heated with sodium azide in anhydrous dimethylformamide at 130 deg C, 3-dimethylamino and 3-dimethylaminomethyleneamino-5-phenyl-1,2,4-oxadiazole are formed, the latter by a new deoxygenative coupling of the azide
