This invention relates to metallocene compounds represented by formula:
wherein M is a group 3, 4, 5 or 6 transition metal atom, or a lanthanide metal atom, or actinide metal atom; E is a substituted or unsubstituted indenyl ligand that is bonded to Y through the two position of the indenyl ring; A is bonded to Y, and is a substituted or unsubstituted cyclopentadienyl ligand, a substituted or unsubstituted heterocyclopentadienyl ligand, a substituted or unsubstituted indenyl ligand, a substituted or unsubstituted heteroindenyl ligand, a substituted or unsubstituted fluorenyl ligand, a substituted or unsubstituted heterofluorenyl ligand, or other mono-anionic ligand, or A may, independently, be defined as E; Y is a phosphorus containing group that is bonded to both E and A, and is bonded via the phosphorus atom to E; and X are, independently, univalent anionic ligands, or both X are joined and bound to the metal atom to form a metallocycle ring, or both X join to form a chelating ligand, a diene ligand, or an alkylidene ligand.
本发明涉及由以下式表示的金属环化合物:其中M是3、4、5或6族过渡金属原子,或镧系金属原子,或锕系金属原子;E是通过茚环的2位与Y键合的取代或未取代的茚基配体;A与Y键合,可以是取代或未取代的环戊二烯基配体、取代或未取代的杂环戊二烯基配体、取代或未取代的茚基配体、取代或未取代的杂茚基配体、取代或未取代的芴基配体、取代或未取代的杂芴基配体或其他单负离子配体,或者A可以独立地被定义为E;Y是含磷基团,通过磷原子与E和A键合;X是独立的单价阴离子配体,或者两个X连接并与金属原子结合形成金属环,或两个X连接形成螯合配体、二烯配体或烷基亚胺配体。
