Abstract:
1. A process for producing a metallocene compound of formula (3); wherein R 1 , R 2 , R 3 and R 4 independently denote a hydrogen atom, a halogen atom, a substituted or unsubstituted C 1-20 alkyl, a substituted or unsubstituted C 6-20 aryl, or a substituted or unsubstituted C 7-20 aralkyl; R a silyl substituted with a substituted or unsubstituted C a silyloxy substituted with a substituted or unsubstituted C an amino substituted with a substituted or unsubstituted C R a substituted or unsubstituted C a silyl substituted with a substituted or unsubstituted C a silyloxy substituted with a substituted or unsubstituted C an amino substituted with a substituted or unsubstituted C M denotes a transition metal atom of Group 4 of the Periodic Table; X an amino substituted with a substituted or unsubstituted C R which process comprises reacting a silicon-substituted cyclopentadiene compound of formula (1); wherein R 1 to R 10 independently denote same as described above; R 11 denotes a substituted or unsubstituted hydrocarbon group or a tri-substituted silyl; R a transition metal compound of formula (2); wherein M denotes same as described above; X an amino substituted with a substituted or unsubstituted C n denotes 0 or 1, in a solvent containing an aromatic hydrocarbon.
