A novel four-membered 1,3-ditelluretane dialdehyde 8/9 was synthesized from trimethylsilylethynyl tellurolate. The dialdehyde was transformed into extended tetrathiafulvalenes (14 and 15). These are the first examples of ditelluretane spaced TTF derivatives.
SYNTHESIS OF CIS- AND TRANS-2,4-DIBENZYLIDINE-1,3-DITELLURETAN FROM SODIUM PHENYL ACETYLIDE AND TELLURIUM METAL; A REINVESTIGATION AND STRUCTURE PROOF

Reaction of sodium phenyl acetylide with tellurium metal and subsequent protonation yields the title comounds, rather than a 1,3-ditellurole as recently reported.

, p. 828 - 829 (2007/10/02)
Protonation of sodium phenylethynyltellurolate with trifluoroacetic acid afforded trans-2,4-dibenzylidine-1,3-ditelluretan as the minor product, and cis- and trans-2,6-diphenyl-1,4-ditellurafulvenes (4) and (5) as the major products which latter represent the first examples of 1,3-ditelluroles.
cis-3,5-DIBENZYLIDENE-1,2,4-TRITELLUROLE, A NOVEL ORGANOTELLURIUM HETEROCYCLE
Lakshmikantham, M. V.,Cava, Michael P.,Albeck, Michael,Engman, Lars,Carroll, Patrick,et al.
, p. 4199 - 4200 (2007/10/02)
The reaction of sodium phenylethynyltellurolate with etheral hydrogen chloride afforded, in addition to trans-2,4-dibenzylidene-1,3-ditelluretane, a product shown to be the title compound by an X-ray crystallographic analysis.
UNSATURATED THIOLATES AND THEIR ANALOGS IN CYCLOADDITION REACTIONS VII. ALKALI-METAL SALTS OF 2-ARYLETHYNETELLUROL
Laishev, V. Z.,Petrov, M. L.,Petrov, A. A.
, p. 1842 - 1847 (2007/10/02)
Salts of 2-arylethynetellurols were obtained by the reaction of alkali-metal arylacetylides with tellurium in dimethyl sulfoxide.Treatment of the products with an ether solution of hydrogen chloride led to 2,4-di (p-R-benzylidene)-1,3-ditelluranes, and treatment with water (or oxidation with iodine) led to di (2-arylethynyl)tellurides.Sodium 2-phenylethynetellurolate enters into a cyclization reaction with carbon bisulfide and dimethyl acetylenedicarboxylate.In the latter case nucleophilic addition products are formed.The initial product in the reaction of sodium 2-phenylethynetellurolate with dithylamine is the unstable N,N-diethylphenylthioacetamide.
