✦ Synopsis

Synthesis, Properties and Electronic Structure of 1,2,4-Triazolo(1,2a) pyridazinium and Benzotriazolo(1,2-a)pyridazinium Salts. -Acylation of 1-methallyltriazole derivatives in the presence of HClO4 provides the title triazolopyridazinium salts (III) or (VI), resp., which represent novel heterocyclic systems. Salt (III) undergoes hydrolytic cleavage in alkaline solution to give the pyridazine (IV). -(VOSHCHULA, V. N.; VYSOTSKII,
