摘要： Disclosed herein is a method of preparing 1-octene at high activity and high selectivity while stably maintaining reaction activity by tetramerizing ethylene using a chromium-based catalyst system comprising a transition metal or a transition metal precursor, a cocatalyst, and a P-C-C-P backbone structure ligand represented by (R1)(R2)P-(R5)CHCH(R6)-P(R3)(R4).
