PROCESS FOR PRODUCTION OF MESO-FORM AND RACEMIC-FORM METALLOCENE COMPLEXES

摘要

A method for producing an anionized meso-form double-cross-linked ligand represented by formula (3), including: bringing a compound represented by formula (1) into contact with a compound represented by formula (2) at -25°C or less; and introducing an anionizing agent within 5 hours after the contact, wherein R 1 to R 10 are independently a hydrogen atom, a hydrocarbon group having 1 to 20 carbon atoms, or the like; A and A' are independently a cross-linking group containing an atom belonging to the 14 th group of the periodic table; M and M' are independently an atom belonging to the 1 st or the 2 nd group of the periodic table.
