(26–28) were prepared from corresponding diamines and SeO2 and 26 also from the diamine and SeCl4. Compounds synthesized were characterized by multinuclear NMR (particularly 1H, 19F, 77Se), compounds 1, 2, 4, 7, 8, 16 (salt with 2 HCl), 19, 26, 28 and 32 by single-crystal X-ray diffraction, and quinoxalines 1–8, thiadiazole 22 and selenadiazoles 27 and 28 by UV-vis and fluorescence techniques.
