This invention relates to a 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 an indenyl ligand that is substituted with a PR
2
group in the two position of the indenyl ligand, where each R is, independently a hydrocarbyl, substituted hydrocarbyl, halocarbyl, or substituted halocarbyl substituent, and additionally, E may be substituted with 0, 1, 2, 3, 4, 5 or 6 R
n
where each R
n
is, independently, a hydrocarbyl, substituted hydrocarbyl, halocarbyl, substituted halocarbyl, silylcarbyl, substituted silylcarbyl, germylcarbyl, or substituted germylcarbyl substituent, and optionally, two or more adjacent R
n
substituents may join together to form a substituted or unsubstituted, saturated, partially unsaturated, or aromatic cyclic or polycyclic substituent; A 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 or as X; each X is, independently, an univalent anionic ligand, 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.
本发明涉及一种由以下公式表示的金属茂化合物:其中M是3、4、5或6族过渡金属原子、镧系金属原子或锕系金属原子;E是一个在茂环的2位被PR2基取代的茚烯配体,其中每个R都是独立的,可以是一个碳氢化合物、取代的碳氢化合物、卤代碳氢化合物或取代的卤代碳氢化合物基团,此外,E可以被0、1、2、3、4、5或6个Rn取代,其中每个Rn都是独立的,可以是一个碳氢化合物、取代的碳氢化合物、卤代碳氢化合物、取代的卤代碳氢化合物、硅基碳氢化合物、取代的硅基碳氢化合物、锗基碳氢化合物或取代的锗基碳氢化合物基团,而且,两个或更多相邻的Rn取代基团可以结合在一起形成取代或未取代的饱和、部分不饱和或芳香环或多环取代基团;A是一个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、取代或未取代的茚烯配体、取代或未取代的杂茚烯配体、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阴离子配体,或者A可以独立地被定义为E或X;每个X都是独立的一价阴离子配体,或者两个X结合并与金属原子结合形成金属环烷基,或两个X结合形成螯合配体、二烯配体或烷基亚胺配体。
