Criss-cross Cycloadditions on Ketazines Derived from Alicyclic Ketones
The reactivity of alicyclic ketazines in criss-cross cycloadditions was investigated. They react with potassium cyanate and ammonium thiocyanate in the presence of acetic acid to form spirocyclic perhydro[1,2,4]triazolo[1,2-a][1,2,4]triazole-1,5-diones ...

A new luminescent Ru(terpy) complex incorporating a 1,2,4-triazole based σ-donor ligand [PDF]
The mononuclear compound [Ru(terpy)L], where H2L is 2,6-bis(1,2,4-triazol-3-yl)pyridine, shows an emission lifetime of 65 ns, about 300 times longer than that observed for the parent [Ru(terpy)3]2 ...

Synthesis of 2-(3-chloro-4-nitro-1-benzothien-2-yl)-1,3,4-oxadiazole-1,3,4-thiadiazole and 5-(3-chloro-4-nitro-1-benzothien-2-yl)-4H-1,2,4-triazole-3-thiol [PDF]
In this paper the synthesis of some substituted 1,3,4-oxadiazole, 1,3,4-thiadiazole and 1,2,4-triazole is reported. 3-chloro-4-nitro-2-chloro carbonyl benzo [b] thiophene(1) was synthesized from 2-nitrocinnamic acid by its reaction with thionyl chloride ...
