M. Minoura et al., SYNTHESIS, STRUCTURE, AND REACTIVITY OF 1,4,2-OXATELLURAZOLE - A NOVEL TELLURIUM-CONTAINING HETEROCYCLE, Phosphorus, sulfur and silicon and the related elements, 93(1-4), 1994, pp. 403-404
A novel tellurium containing heterocycle, 1,4,2-oxatellurazole, was ch
aracterized by X-ray crystallographic analysis which showed a remarkab
ly small C-Te-C bond angle (79.4 degrees), and its 1,3-dipolar cyclore
version is discussed.
