Abstract:
The present invention relates to a catalyst composition and a process for di-, tri- and/or tetramerization of ethylene, wherein the catalyst composition comprises a chromium compound, a ligand of the general structure (A) R1R2P—N(R3)—P(R4)—N(R5)—H or (B) R1R2P—N(R3)—P(R4)—N(R5)—PR6R7, or any cyclic derivatives of (A) and (B), wherein at least one of the P or N atoms of the PNPN-unit or PNPNP-unit is member of a ring system, the ring system being formed from one or more constituent compounds of structures (A) or (B) by substitution and a co-catalyst or activator.
