Halogen substituted metallocene compounds are described and comprise one or more monocyclic or polycyclic ligands that are pi-bonded to the metal atom and include at least one halogen substituent directly bonded to an sp

carbon atom at a bondable ring position of the ligand, wherein the or at least one ligand has one or more ring heteroatoms in its cyclic structure. When combined with a suitable activator, these compounds show activity in the polymerization of olefins, such as ethylene and propylene.
描述了卤代取代的茂金属化合物,包括一个或多个与金属原子π键结合的单环或多环配体,并且至少包括一个卤素取代基直接键合到配体的可键合环位置上的sp2碳原子,其中该配体或至少一个配体在其环状结构中具有一个或多个环异原子。与适当的活化剂结合时,这些化合物在烯烃聚合反应中显示出活性,例如乙烯和丙烯。
