1,5-Diaminotetrazole was reacted in 'one-pot' with one carbon cyclizing reagents to afford the corresponding 1,2,4-triazolo[1,5-d]tetrazoles. Analogues reactions with nitrous acid, benzil, diethyl oxalate, pyruvic acid and ethyl acetoacetate afforded tetrazoloheterocycles for biological interest.

New bridgehead nitrogen containing heterocycles such as thiazolotriazine (IVa and IVb), imidazolotriazine (IVc), triazinotriazine (IVd and IVe) and oxadiazolotriazine (IVf) and several of their derivatives (V) have been prepared by reacting their respective hydrazine (II) with ethylpyruvate and phenyl glycoxalic acid.The diazotization of hydrazine (II) furnished the reactive intermediates (VI) (azido form) and (VII) (tetrazole form) depending on the structure of hydrazines.These intermediates have been used to synthesise bridgehead nitrogen pyrimidine derivatives (VIII) by reacting them with diethyl fumarate.The spectral and chemical evidences show that diazotised products obtained from 2-hydrazino-4-phenyl thiazole (IIa) and 2-hydrazino benzothiazole (IIb) exist in tetrazole form (VIIa) and (VIIb), respectively, whereas the remaining four (IIa-IIf) remain in the azido form (VIc-VIf) in the solid state.
