Addition of ICI to Vinylsilanes

Abstract
In an earlier paper1 from this laboratory describing the stereoselective synthesis of vinyl halides from vinylsilanes, we reported the formation of trans-l-iodo-l-hexene from cis-l-tri-methylsilyl-l-hexene by reaction with an acyl hypoiodite followed by fluoride ion-induced elimination of the elements of trifluoro-acetoxytrimethylsilane: Serious drawbacks to this approach include low yields of adduct formation and use of an expensive silver reagent.
