摘要： Catalyst compositions are prepared by contacting a palladium source and 1,3,5,7-tetramethyl-6-(2,4-dimethoxyphenyl)-2,4,8-trioxa-6-phosphaadamantane and a methoxyocta-diene compound, in a primary aliphatic alcohol, under suitable conditions including a ratio of equivalents of palladium to equivalents of 1,3,5,7-tetramethyl-6-(2,4-dimethoxyphenyl)-2,4,8-trioxa-6-phosphaadamantane ranging from greater than 1:1 to 1:1.3. The result is a complex of palladium, a 1,3,5,7-tetramethyl-6-(2,4-dimethoxyphenyl)-2,4,8-trioxa-6-phosphaada-mantane ligand, and a ligand selected from a methoxyoctadiene ligand, an octadienyl ligand, or a protonated octadienyl. Such complexes may, in solution, exhibit surprising solubility and storage stability and are useful in the telomerization of butadiene, which is a step in the production of 1-octene.

摘要： A catalyst and a process for using the catalyst are presented. The catalyst is a heterogeneous catalyst and includes active metal halides bonded to functional groups. The functional groups are bonded to a polymeric backbone to form the structure supporting the catalyst. The catalyst is useful for the dimerization of acetylene to convert the acetylene to a larger hydrocarbon, and in particular to dimerize acetylene to vinylacetylene.

摘要： Disclosed herein are processes for tandem alkene dehydrogenation/alkene dimerization using an iridium pincer complex catalyst on a support comprising magnesium silicates (e.g., Florisil®). The reaction process comprises providing an iridium pincer complex bound to a solid support comprising magnesium silicates; providing a gaseous alkane feedstock comprising at least one alkane; and contacting the gaseous alkane feedstock with the iridium pincer complex bound to the solid support in the presence of a hydrogen acceptor to form dimerized alkenes. The processes disclosed herein can accomplish facile, low-temperature tandem transfer dehydrogenation of alkanes and dimerization of alkenes with unprecedented TONs at a reasonable rate of conversion.
