A series of new symmetrical s-tetrazine derivatives, coupled via a 1,4-phenylene linkage with a 4H-1,2,4-triazole ring, were obtained. The combination of these two rings in an extensively coupled system has significant potential applications, mainly in op
Highly fluorescent 1,2,4,5-tetrazine derivatives containing 1,3,4-oxadiazole ring conjugated via a 1,4-phenylene linker

Symmetrical and unsymmetrical 1,2,4,5-tetrazine derivatives containing 1,3,4-oxadiazole ring were obtained in high yields using commercially-available 4-cyanobenzoic acid, hydrazine hydrate and carboxylic acid chlorides. The few-step transformation involved the Pinner reaction and the subsequent mild oxidation of 1,4-dihydro-1,2,4,5-tetrazines using hydrogen peroxide at room temperature. The obtained compounds exhibited luminescent properties and large quantum yields.

Three series of substituted 1,3,4-oxadiazoles were studied by 17O NMR spectroscopy. Chemical shifts values were correlated with empirical Hammett parameters as well as calculated bond lengths and chemical shielding values.
