Abstract

Recent reports on the halogenation of alkenes to vic-dihalogenides by treatment with diaryltellurium () derivatives as well as the reported debromination of vic-dibromides to afford olefins with diaryl telluride () derivatives suggest that these reactions are reversible and the equilibria is shown in eqn.(1). 1–4 On the other hand, organoselenium () derivatives are useful as halogenating agents for olefinic substrates since similar ...
