## Abstract Some new 1,2,3βtriazolo[4,5β__e__]β1,2,4βtriazolo[3,4β__c__]pyrimidmes were prepared starting from the corresponding 1,2,3βtriazolo[4,5β__d__]pyrimidines __via__ the formation of the 1,2,4βtriazole ring. Thus suitable hydrazino derivatives 6 were condensed with triethyl orthoformate, tr
## Abstract The reaction of benzoyl isothiocyanates and methoxycarbonyl isothiocyanate with 4βaminoβ4,5βdihydroβ3β(methylthio)β1,2,4βtriazinβ5βones in acetonitrile gave several substituted 4__H__β1,3,4βthiadiazolo[2,3β__c__]β1,2,4βtriazinβ4βones VIaβh instead of the expected thioureas. In addition,
