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.
