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
Reaction of Bis(<i>trans</i>-1-hexenyl)methylborane with Two Molar Equivalents of Methylcopper(I). Evidence for the Presence of<i>trans</i>-1-Hexenylcopper(I) as an Intermediate
Bis(trans-1-hexenyl)methylborane, prepared by the reaction of bis(trans-1-hexenyl)chloroborane with methyllithium, was treated with 2 molar equivalents of methylcopper(I) at −78 °C to give (5E,7E)-5,7-dodecadiene quantitatively. The result indicates the presence of trans-1-hexenylcopper(I) intermediate.
