Abstract
A group of exocyclic pyridyl-phosphinimine ligands have been prepared in excellent yields by oxidizing trip henylphosphine with 2-azidomethylpyridines. These ligands reacted with group 8--10 transition metals to form various late transition metal complexes (e.g. [Ph3P=NCH2(2-Py)]NiBr 2 36) which have been characterized and evaluated for olefin polymerization activity. We found that these complexes are not active for ethylene polymerization or oligomerization. In a similar sense, nickel complexes 55 and 56 were synthesized by the reaction of nickel dihalide with a chiral bis-diiminophosphorane ligands. The corresponding ligand was prepared by deprotonation of R-2,2' -diamino-1,1'-binaphthalenetriphenyldibromide by a strong base. The complexes were seemed to be inactive for ethylene polymerization, and were therefore not tested for alpha-olefins polymerization.Dept. of Chemistry and Biochemistry.
