ABSTRACT:
Internal olefins in the 4 to 30 carbon number range are isomerized to alpha olefins, utilizing cyclopentadienyltantalum compounds in either a catalyst or reagent mode. Under a preferred practice of the process of this invention, internal olefin is contacted with the reagent to form a first complex, alpha olefin is liberated from said first complex upon contact with carbon monoxide to yield a second complex, and reagent is regenerated from said second complex upon contact with water.
