3-Benzotellurepines: the first examples of tellurepines
Abstract
Reaction of o-diethynylbenzene with sodium telluride in the presence of hydrazine hydrate gives 3-benzotellurepine 2, which is converted into the 3,3-dihalogeno derivatives 3 by treatment with sulphuryl chloride or bromine; these compounds are the first examples of tellurepines.
