Synthesis, structure, and thermolysis of a novel spirotellurane bearing two 1,2-oxatelluretane rings, 1,5-dioxa-4λ4-telluraspiro[3.3]heptane: oxirane and olefin formation reactions

The first 1,5-dioxa-4λ4-telluraspiro[3.3]heptane was synthesized and its structure was determined by X-ray analysis. This tellurane gave the corresponding oxirane and olefin, as well as alcohol, upon heating, which were shown to be formed via a radical pathway.
