Ipso halodestannylation of I,1-bis(tributylstannyl)ethenes with one equivalent of halogen leads to a variety of 1-halovinylstannanes. In certain cases, these reactions exhibit high levels of stereoselectivity. A plausible mechanistic pathway is advanced in order to explain the stereochemical outcome of these reactions. Addition of two equivalents of halogen affords the corresponding 1,1-bis-haloalkenes complementing existing methodology (e.g. Corey-Fuchs reaction) for the preparation of these useful synthetic intermediates.
