cyclopentadienyl- and imidazolyl-phosphine-containing Ru-based complexes bearing a different degree of the Cp-ring methylation has been attempted. According to experimental and structural data the steric factors prevented the formation of the last complex in the series that contains permethylated Cp ring. These complexes were then subjected to alkene isomerization using 1-hexene. The rate of isomerization
Unsaturated and hydrogenated polyalpha-olefin products can be made with a high selectivity toward vinylidenes and tri-substituted vinylenes combined, a high selectivity toward vinylidenes, and a low selectivity toward 1,2-di-substituted vinylenes by using a catalyst system comprising a metallocene compound having the following structure in the polymerization reaction:
