  Synthesis of 1,2-ditellurolane derivatives

  摘要：

  Stable derivatives 4 and 5 of the elusive 1,2-ditellurolane (3) have been synthesized. Ditellurolane 4 was subjected to X-ray crystallographic analysis. The unusual blue color of these molecules has been attributed to the small dihedral angle associated with the rigid ring. The most remarkable reaction of these systems is the reversible monoprotonation of the Te-Te moiety.

  More than 40 new 4- to 12-membered ring heterocycles containing various combinations of Group 14 and 16 elements Si, Sn, S, Se, and Te have been synthesized and fully characterized. Synthesis of these small-ring as well as medium-ring (mesocyclic) heterocycles from alpha,omega-dihalides is facilitated by the presence of gem-dialkylsilyl and gem-dialkylstannyl groups in the precursors.

• Synthesis of 1,3-bis(organylchalcogeno)propanes and 1,2-dichalcogenolanes having different chalcogen atoms in the molecule

  Oligomeric trimethylene dichalcogenides and the corresponding 1,2-dichalcogenolanes having both similar and different chalcogen atoms in the molecule were synthesized by reactions of 1-bromo-3-chloropropanes with two elemental chalcogens (S, Se; S, Te; Se, Te) activated by the system hydrazine hydrate-alkali. Reductive cleavage of the oligomeric products in the system hydrazine hydrate-alkali, followed by alkylation with methyl iodide or ethyl bromide gave 1,3-bis(alkylchalcogeno)propanes. The latter were also obtained from the corresponding dialkyl dichalcogenides and 1-bromo-3-chloropropane in the alkaline reducing system.

  1,2-Ditellurolane is an extremely unstable heterocyclic compound which can be maintained in solution in the presence of nitrosodurene for several days. It is proposed on the basis of UV spectroscopy and H-1 NMR spectroscopy that a complex is formed which determines the stability of 1,2-ditellurolane. It is shown that stabilized 1,2-ditellurolane can be used in organic synthesis.
