Abstract

The reaction of Li₂[1,2-{N(PMes₂)}₂C₆H₄], formed in situ from n-BuLi and the corresponding amines, with 1 equiv. of [NiBr₂(DME)] gives [Ni{1-N(PMes₂)-2-N(μ-PMes₂)C₆H₄-κ³N,N′,P-κ¹P′}]₂ (1). After activation by methylalumoxane (MAO), 1 is a highly active catalyst in the oligomerization and isomerization of α-olefins such as ethene, propene, isobutene, 1-hexene and 1,5-hexadiene. For ethene oligomerization turnover frequencies (TOFs) range from 3000 to 79015 h^-1, depending on the reaction conditions. The TOF for propene oligomerization reaches 1 190 730 h^-1. To our knowledge, catalyst 1, activated by MAO, is the most active catalyst for the oligomerization of propene and outperforms the best known complexes for this reaction. In the reactions with 1-hexene, 1,5-hexadiene and isobutene dimerization and isomerization products were observed.
