Oligomerization of α-olefins by the dimeric nickel bisamido complex [Ni{1-N(PMes 2 -N(μ-PMes 2 )C 6 H 4 -κ 3 N , N' , P ,-κ 1 P' }] 2 activated by methylalumoxane (MAO)

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 ac Show more
