Title: Ethylene Dimerization/Polymerization Catalyzed by (Adamantylimido)vanadium(V) Complexes Containing (2-Anilidomethyl)pyridine Ligands: Factors Affecting the Ethylene Reactivity
Abstract:V(N-1-adamantyl)Cl2[2-(2,6-Me2C6H3)NCH2(C5H4N)] showed both remarkable activity and selectivity (from 92 through >99.5% selectivity) in ethylene dimerization in the presence of MAO or MMAO, and the ac...V(N-1-adamantyl)Cl2[2-(2,6-Me2C6H3)NCH2(C5H4N)] showed both remarkable activity and selectivity (from 92 through >99.5% selectivity) in ethylene dimerization in the presence of MAO or MMAO, and the activity increased linearly upon increasing the ethylene pressure. The same reaction in the presence of Et2AlCl or Me2AlCl afforded ultrahigh molecular weight polyethylene. Both the ESR spectra and the 51V NMR spectra suggest that the chelate anionic donor ligand plays an important role in stabilization of the oxidation state in the catalyst solution even containing Al alkyls.Read More
