摘要:
A transition metal complex represented by general formula (1) (wherein M1 is a Group 4 transition metal of the periodic table; A is a Group 16 element of the periodic table; B is a Group 14 element of the periodic table; C¿p?1 is a group having a cyclopentadiene-type anionic skeleton; X?1, X2, R1, R2, R3, R4, R5 and R6¿ are each independently hydrogen, halogeno, optionally halogenated C¿1?-C20 alkyl, optionally halogenated C1-C20 substituted silyl or the like, or alternatively R?1, R2, R3, R4, R5 and R6¿ may be united arbitrarily to form a ring); a process for the preparation thereof; an intermediate of the transition metal complex; a process for the preparation of the intermediate; a polymerization catalyst for olefins containing the transition metal complex; and a process for producing olefin polymers.
摘要:
A process for producing cyclopentadienyl metal salts which comprises reacting a cyclopentadiene derivative with a metal hydride in the presence of an amine compound; and a process for producing cyclopentadiene derivatives represented by general formula (3) by utilizing this reaction. In said formula, A represents a Group 16 element of the Periodic Table; B represents a Group 14 element; R to R each represents alkyl, etc.; and R represents a hydrocarbon group or a trisubstituted silyl. By using these processes, not only a variety of cyclopentadienyl metal salts but cyclopentadiene derivatives can be produced in high yields with high conversions without using an expensive reagent or low-temperature facilities.
