摘　　要：Researches of late-transition metal complexes for ethylene polymerization and oligomerization have attracted a lot of attention in the last two decades.A large number of late-transition metal complexes with symmetric diimine ligands have been extensively studied.Although the research of unsymmetric diimine late-transition metal complexes was still in the initial stage,some superior performances were observed in olefin polymerization.Recent developments in the research of ethylene polymerization and oligomerization catalyzed by late-transition metal complexes with unsymmetric diimine ligands were summarized in this review,with the influence of complex structure on the catalytic performance of the catalyst analyzed.Researches of late-transition metal complexes for ethylene polymerization and oligomerization have attracted a lot of attention in the last two decades. A large number of late-transition metal complexes with symmetric diimine ligands have been extensively studied. Although the research of unsymmetric diimine late-transition metal complexes was still in the initial stage, some superior performances were observed in olefin polymerization. Recent developments in the research of ethylene poly- merization and oligomerization catalyzed by late-transition metal complexes with unsymmetric diimine ligands were summarized in this review, with the influence of complex structure on the catalytic performance of the catalyst analyzed.
