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.
Claims14
A process for the isomerization of an internal olefin in the carbon number range from 4 to about 30 to an alpha olefin, which comprises steps for:
- (a) contacting a compound of the formula Cp.sub.2 TaH.sub.3, wherein Cp represents an optionally alkyl-substituted cyclopentadienyl, indenyl, or fluorenyl radical, with the internal olefin to form a complex, and
- (b) liberating alpha olefin from said complex.
A process for the isomerization of an internal olefin in the carbon number range from 4 to about 30 to an alpha olefin, which comprises steps for (a) contacting the internal olefin with a reagent of the formula Cp.sub.2 TaH.sub.3, wherein Cp represents a cyclopentadienyl group or an alkyl-substituted cyclopentadienyl group, to form a first complex, (b) contacting said first complex with carbon monoxide to liberate alpha olefin therefrom and to form a second complex, and (c) contacting said second complex with water to regenerate Cp.sub.2 TaH.sub.3 reagent.
