Abstract
Abstract Reaction of alkylphenylacetylenes with tellurium(IV) tetrachloride in carbon tetrachloride gives Z-(2-chlorovinyl)tellurium (IV) trichloride derivatives in over 75% yield, which afford the corresponding Z-chloroiodoalkenes or Z-bromochloroalkenes in good yields by halogenodetelluration with iodine in acetonitrile or N-bromosuccinimide in carbon tetrachloride.
