Add to ORKGCondensations of tri-, di-, and mono-ethylene glycol bis-(2-mercaptoethyl) ethers (6a, b, c) and bis(mercaptoethyl) ether and the thioether (6d, e) with 4,6-bis(chloromethyl)-2,5-dimethoxytropone (5), which was prepared from 5-hydroxytropolone in a three-step sequence, gave dithio-crown ethers (7a, b, c and 8d, e), of which, 7a, b, c selectively formed inclusion complexes with Hg2+. The complexes with 7a, b, c were quantitatively dissociated by acidification with dil hydrochloric acid. Thus, an effective method for extraction of Condensations of tri-, di-, and mono-ethylene glycol bis-(2-mercaptoethyl) ethers (6a, b, c) and bis(mercaptoethyl) ether and the thioether (6d, e) with 4,6-bis(chloromethyl)-2,5-dimethoxytropone (5), which was prep...
