| Abstract: | Telluraxanthene was obtained by intramolecular electrophilic cyclization of 2-trichlorotelluriodiphenylmethane with subsequent reduction of the intermediately formed 10,10-dichlorotelluraxanthene. The chemical reactions that occur at the tellurium atom and the methylene group of telluraxanthene were studied. The lower limit of the activation energy of pyramidal inversion at the onium tellurium atom in telluroniaxanthenyldimedone ylid was determined by PMR spectroscopy.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 10, pp. 1342–1349, October, 1980. |
