Document Type and Number:
Japanese Patent JP2005531666
Kind Code:
A
Abstract:
The invention relates to a catalyst composition comprising a salt of a non- or weakly coordinating anion, said non- or weakly coordinating anion comprising at least one metal or metalloid ion M with valency v+, v representing an integer between 1 and 5, and at least one bidentate ligand coordinating to this metal or metalloid ion, and a catalyst that can be activated by said non- or weakly coordinating anion, characterized in that said bidentate ligand is a bidentate monoanionic ligand of formula (I): (R1qA1-X-A2R2r), wherein X represents a bridging moiety; A1 and A2 are each independently chosen from the group comprising N, O, P, S, and C; R1 and R2 are each independently chosen from the group comprising an optionally substituted linear or branched (hetero)alkyl group, an optionally substituted (hetero)aryl group, and a Si containing group; and q and r each independently represent an integer with 0<=q, r<=2.
