Zusammenfassung: | FIELD: organic chemistry, analytical chemistry. ^ SUBSTANCE: invention relates to synthesis of novel analytical reagents of chelate-forming type. Synthesized compounds represent chelate-forming dibenzo-containing five-membered cyclic compounds comprising two symmetric beta-dicarbonyl substitutes bound covalently with fluorine-containing radicals of the general formula (1): , wherein X means -CH2, oxygen (O), sulfur (S) atom, -NR; if X means -CH2 then R means hydrogen atom (H); R2 means -C(O)CH2C(O)Rf wherein Rf means -(CF2)nY wherein n = 1-6, and at n = 1 Y means H, F, Cl, Br, -OCF3, -OCH3, -OC3F7, -OCF2-CF2-OCF3, -C6F5, -C(O)OAlk wherein Alk means hydrocarbon radical; at n = 2 Y means H, F, Cl, Br, -OCF3, -OC3F7, -OCF2-CF2-OCF3, -C(O)OAlk; at n = 3, 5 or 6 Y means F, -C(O)OAlk; at n = 4 Y means H, F, Cl, -C(O)OAlk; if X means O, S or -NR then R means H or Alk, R2 means H, R1 means -C(O)CH2C(O)Rf. Invention can be used in field of luminescent-spectral analysis, in particular, for clinical diagnosis of object of biogenic origin, and in technique field for using as extractants of heavy and rare-earth metal ions for their extraction and/or purifying from their impurities of sewage and contour waters. ^ EFFECT: valuable medicinal and technical properties of compounds. ^ 1 cl, 19 dwg, 19 ex |
