摘要： The present disclosure provides a method and a catalyst for selective oligomerization of ethylene. The raw material for the catalyst consists of a dehydropyridine annulene-type ligand, a transition metal compound, and an organometallic compound in a molar ratio of 1:0.5-100:0.1-5000. The present disclosure also provides a method for selective oligomerization of ethylene accomplished by using the above-mentioned catalyst. The catalyst for selective oligomerization of ethylene has high catalytic activity, high selectivity for the target products 1-hexene and 1-octene, and low selectivity for 1-butene and 1-C10+.
