摘要：
A new procedure has been proposed for the synthesis of 8-aryl[1,2,4]triazolo[1,5-d][1,2,4]-triazin-5(6H)-ones by reaction of 6-aryl-1,2,4-triazin-3(2H)-ones with hydrazides derived from aliphatic, aromatic, and heterocyclic carboxylic acids. The process invloves nucleophilic substitution of hydrogen (SNH)in aryltriazinones, oxidative closure of azole ring, and Dimroth rearrangement.
