  2-Substituted Isotellurochromenium Salt Derivatives: Preparations, Structures, Spectroscopic Properties

  摘要：

  Several types of novel isotellurochromenium salt derivatives (2-10) were prepared from the isotellurochromenes (1). The isotellurochromenium tetrafluoroborates (2), triflates (3-5), tosylates (6) and mesylates (7) are telluronium salts, and the dihalogenoisotellurochromenes (8-10) are telluranes. The molecular structures of the isotellurochromenium tosylate (6a) and the dichloroisotellurochromene (8a) were characterized by an X-ray crystallographic analysis using the 3-tert-butyl derivatives.

  An alternative, simple and practical preparation of benzo[b]-tellurophene, 1H-isotellurochromene, and 1-benzo- and 3-benzotellurepines by taking advantage of the tin-tellurium replacement reaction from the corresponding five-, six- and seven-membered tin-containing heterocycles was achieved.
