## Abstract **Dedicated to Professor András Messmer on the occasion of his 80^th^ birthday** The reaction of differently substituted 5‐amino‐1,2,4‐triazoles (**5**) with isothiourea derivatives (**3**) to yield isomeric 5,7‐diamino‐1,2,4‐triazolo[1,5‐__a__][1,3,5]triazines (**6** and **7**), previ
## Abstract Type **6** meso‐ionic [1,2,4]triazolo[5,1‐__c__]thiadiazoles were synthesised by oxidation of the corresponding __N__‐methyl‐__N__'‐(substitutedbenzal)‐5‐amino‐3‐substituted‐1,2,4‐triazol‐1‐yl)thiohydrazide (**3**) type bases or their [1,2,4]triazolo[5,1‐__d__][1,2,3,6]tetrazepin‐5‐thio
## Abstract Some 1,2,4‐triazolo[1,5‐__a__]pyrimidin‐5‐one derivatives 1 and their alicyclic condensed ring analogues 2‐3 were converted through the corresponding “imino chlorides” 4‐6 to the oximes 7‐9. The “__E__” isomeric structure of the products obtained was proven with the use of cmr using the
