Hydroxyphenylbenzazole compounds that are useful for the selective detection of zinc, aluminum, chromium, and iron cations in vitro and in vivo. The Hydroxyphenylbenzazole compounds include a 2-hydroxyphenyl group bound to a single benzazole group; a first ligand group that is a Schiff base moiety; and a second ligand group selected from a Schiff base moiety and a hydroxyl group

The reactivity and catalytic performance of 2-ethylpyrido[1,2-c][1,2,4]-triazol-3-ylidene 6 have been comprehensively investigated. The carbene 6 has shown unusual properties owing to the effect of the pyrido-annulation. While formohydrazide 8 and hydrazine 9 are obtained via the destruction of the triazole skeleton of the carbene, 3-((1Z,3E)-4-(1H-pyrrol-1-yl)buta-1,3-dienyl)-1-ethyl-1H-1,2,4-triazole 10 is achieved through the cleavage of the C–N bond of the pyridine ring. The carbene 6 has turned out to be a powerful catalyst in a variety of organocatalyzed and Pd(II)-catalyzed transformations.
