A process for producing a substituted metallocene compound comprises reacting a first compound with a transfer-agent, wherein the first compound comprises a complex of a transition metal atom selected from Group 3, 4, 5 or 6 of the Periodic Table of Elements, or a lanthanide metal atom, or actinide metal atom and at least one monocyclic or polycyclic ligand that is pi-bonded to M and is substituted with at least one halogen or sulfonate substituent and the transfer-agent comprises a hydrocarbyl, substituted hydrocarbyl, halocarbyl, substituted halocarbyl, silylcarbyl, or germylcarbyl radical capable of replacing said at least one halogen or sulfonate substituent of said first compound under reaction conditions.
生产取代基金属环化合物的方法包括将第一化合物与转移剂反应,其中第一化合物包括周期表元素第3、4、5或6组中选择的过渡金属原子的配合物,或者是镧系金属原子、锕系金属原子,以及至少一个与M形成π键的单环或多环配体,该配体被至少一个卤素或磺酸酯基取代,转移剂包括能够在反应条件下取代所述第一化合物中的至少一个卤素或磺酸酯基的烃基、取代烃基、卤代烃基、取代卤代烃基、硅烃基或锗烃基自由基。
