F 12 Facile Synthesis of 6-aryl-3-pyridyl-1,2,4-triazines as a key step towards hightly fluorescent 5-substituted bipyridines and their Zn(II) and Ru(II) complexes [Electronic resource] / V. N.

Kozhevnikov // Tetrahedron. - 2008. - Vol. 64, № 37. - P8963-8973 : рис., табл. - Библиогр. : с. 8973 (21 назв.) . - ISSN 0040-4020 Рубрики: ХИМИЧЕСКИЕ НАУКИ Аннотация: A wide series of substituted bipyridines were obtained through the synthesis of 1,2,4-triazines and their aza Diels–Alder reactions. The reported method facilitates the synthesis of functionally diverse bipyridines that provides fine-tuning of photophysical properties of new ligands and their Zn(II) and Ru(II) complexes. Some of substituted bipyridines exhibit ‘off–on’ fluorescence response toward Zn2+ cations.???? \\\\Expert2\\nbo\\Tetrahedron\\2008, v. 64, N37, p. 8963.pdf |
