## Abstract 2‐Aryl(arylsulfonyl)‐6,7‐dihydro‐2__H__‐imidazo[2,1‐__c__][1,2,4]triazol‐3(5__H__)‐ones and 3‐arylimino‐6,7‐dihydroimidazo[2,1‐__c__][1,2,4]thiadiazoles have been synthesized by intramolecular nucleophilic substitution reactions at the electron‐deficient sp^2^ nitrogen atom of 2‐(hydrox
