摘要:A metallocene complex is represented by the the formulan n(C p R 5 ) n MX k n nwhere C p (each occurrence) is a cyclopentadienyl group; each of the five R substituents on the or each cyclopentadienyl group is independently selected from hydrogen, C 1 to C 30 substituted or unsubstituted hydrocarbyl, halohydrocarbyl, silylhydrocarbyl or silylhalohydrocarbyl, wherein two adjacent R substituents may be joined to form part of a saturated, partially unsaturated or aromatic monocyclic or polycyclic ring structure, and SiR′ 2 NR″ 2 where each of the two R′ substituents is independently selected from hydrogen, C 1 to C 30 substituted or unsubstituted hydrocarbyl, halohydrocarbyl, silylhydrocarbyl or silylhalohydrocarbyl, wherein two adjacent R′ substituents may be joined to form part of a saturated, partially unsaturated or aromatic monocyclic or polycyclic ring structure, and each of the two R″ substituents is independently selected from C 2 to C 30 substituted or unsubstituted hydrocarbyl, halohydrocarbyl, silylhydrocarbyl or silylhalohydrocarbyl, wherein two adjacent R″ substituents may be joined to form part of a saturated, partially unsaturated or aromatic monocyclic or polycyclic ring structure; n is 1 or 2; M is a metal of valence m from Groups 4 to 11 of the Periodic Table of Elements, k is equal to m minus n and the or each X substituent is a univalent anionic ligand, or two X substituents are joined and bound to the metal atom to form a metallocycle ring, or two X substituents are joined to form a chelating ligand, a diene ligand, or an alkylidene ligand, provided that at least one R substituent on the or one cyclopentadienyl group is SiR′ 2 NR″ 2 , provided that at least one R substituent on at least one C p is SiR′ 2 NR″ 2 and provided that one or the C p may be bridged by a bridging group to another C p group, or a heteroatom containing group, where the bridging group replaces one R group on the C p group(s) or a hydrogen on a heteratom containing group.
