摘要： The present invention relates to a catalyst composition and a process for the oligomerization of ethylene to produce 1-hexene or 1-octene, wherein the catalyst composition comprises a chromium compound; an NPNPN ligand of the formula (R1) (R2)N—P(R3)—N(R4)—P(R5)—N(R6)(R7), wherein R1, R2, R3, R4, R5, R6 and R7 are each independently hydrogen, halogen, amino, tri-methylsilyl or C1-C20 hydrocarbyl, preferably straight-chain or branched C1-C10 alkyl, phenyl, C6-C20 aryl or C6-C20 alkyl-substituted phenyl.

摘要： A catalyst composition including: (a) a chromium compound; (b) a ligand of the general structure R1R2P—N(R3)—P(XR7)2, wherein X is O or S, R1, R2, and R3 are each independently C1-C10-alkyl, C6-C20-cycloalkyl, arylalkyl, alkylaryl, or trialkylsilyl, or any cyclic derivatives of the ligand, wherein at least one of the P or N atoms of the PNP-unit is a member of the ring system, the ring system being formed from one or more constituent compounds of the ligand by substitution, and R7 is C1-C10-alkyl, C3-C10-cycloalkyl, arylalkyl, or trialkylsilyl; and (c) an activator or co-catalyst.
