The reactions of alkenylboranes with palladium acetate were investigated. Alkenyldialkylboranes, derived from terminal alkynes, underwent intramolecular migration reaction in the presence of an equimolar amount of palladium acetate and triethylamine to give (E)-olefins. On the other hand, under the same conditions as above or even in the presence of catalyticamounts of palladium acetate, alkenyldialkylboranes

Successive treatments of alkenyldialkylboranes, formed by the reaction of alkynes and sterically hindered dialkylboranes, with alkyllithium and benzenesulfenyl chloride afforded highly pure (E)-alkenes in good or excellent yields.
