Reactions with Hydrazidoyl Halides XII1 Synthesis of Pyrazolo[5,1-c]-1,2,4-triazine, Selenadiazolo[3,2-a]quinazolones, Selenadiazoline, Thiadiazoline and Thiazole Derivatives

Several new pyrazolo[5, 1-c]triazine, selenadiazoline, thiadiazoline, selenadiazolo[3,2-a]quinazolone, and arylazothiazole derivatives were synthesised by the reaction of hydrazonoyl halides with different reagents. The structure of new heterocycles were assigned on the basis of their elemental analysis, spectral data, and alternate synthesis whenever possible.
