TETRAMERISATION OF ETHYLENE

A process for the tetramerisation of ethylene includes contacting ethylene with a catalyst under ethylene oligomerisation conditions. The catalyst comprises a source of chromium, a ligating compound, and an activator. The ligating compound includes a phosphine that forms part of a cyclic structure.

CATALYTIC OLIGOMERIZATION OF OLEFINIC MONOMERS

A catalyst precursor composition comprising: a) a source of chromium, molybdenum or tungsten; b) a first ligand having the general formula (I); [in-line-formulae](R1)(R2)P—X—P(R3)(R4)??(I) [/in-line-formulae] wherein: X is a bridging group of the formula —N(R5)—, wherein R5 is selected from hydrogen, a hydrocarbyl group, a substituted hydrocarbyl group, a heterohydrocarbyl group, a substituted heterohydrocarbyl group, a silyl group or derivative thereof; at least three of R1 to R4 are independently selected from optionally substituted aromatic groups, each bearing a polar substituent on at least one of the ortho-positions; and optionally one of R1 to R4 is independently selected from hydrocarbyl, substituted hydrocarbyl, heterohydrocarbyl and substituted heterohydrocarbyl groups with the proviso that when the group is aromatic it does not contain a polar substituent at any of the ortho-positions; c) a second ligand having the general formula (II); [in-line-formulae](R1′)(R2′)P—X′—P(R3′)(R4′)??(II) [/in-line-formulae] wherein: X′ is a bridging group as defined for X of the first ligand, component (b), of general formula (I); at least R1′ and R2′ of R1′ to R4′ are independently selected from hydrocarbyl, substituted hydrocarbyl, heterohydrocarbyl and substituted heterohydrocarbyl groups with the proviso that when the group is aromatic it does not contain a polar substituent at any of the ortho-positions; and optionally none, one or both of R3′ and R4′ are independently selected from an optionally substituted aromatic group bearing a polar substituent on at least one of the ortho-positions. The present invention also relates to a catalyst system comprising the catalyst precursor composition of the present invention and additional component; d) a cocatalyst. The present invention further relates to a process for the trimerization and tetramerization of olefinic monomers, particularly the trimerization and tetramerization of ethylene to 1-hexene and 1-octene, wherein the process comprises contacting at least one olefinic monomer with the catalyst system of the present invention.
