Claims
- 1. In a process for the telomerization of conjugated diolefin with an active hydrogen-containing telomerization agent in a solvent-containing liquid menstruum under telomerization conditions including the presence of palladium-containing telomerization catalyst which is comprised of a complex of palladium or palladium compound and phosphorus-based ligand, an improvement wherein the solvent comprises dialkylalkylene urea.
- 2. The process of claim 1 in which the dialkylalkylene urea is dialkylethylene urea.
- 3. In a process for the telomerization of conjugated diolefin with an active hydrogen-containing telomerization agent in a solvent-containing liquid menstruum under telomerization conditions including the presence of palladium-containing telomerization catalyst which is comprised of a complex of palladium compound and phosphorus-based ligand to produce substituted alkadiene comprising alpha-substituted alkadiene, an improvement wherein the liquid menstruum comprises dialkylalkylene urea in an amount sufficient to enhance the selectivity of the alpha-substituted alkadiene.
- 4. The process of claim 3 in which the conjugated diolefin comprises butadiene, the telomerization agent comprises water and the alpha-substituted diolefin is octadien-1-ol.
- 5. The process of claim 3 in which the dialkylalkylene urea comprises dialkylethylene urea.
- 6. The process of claim 5 in which the dialkylethylene urea comprises dimethylethylene urea.
