| titleOfInvention | Meso-selective synthesis of ansa-metallocene complexes |
| abstract | Formula (II): [Chemical 1] A ligand starting compound represented by formula (III): [Chemical 2] Comprising the step of reacting with a transition metal compound represented by formula (I): [Chemical 3] In the formulas (I), (II) and (III) above, an ansa-metallocene complex represented by the formula: R 1 and R 1 ′ may be the same or different and each represents hydrogen or an organic group having 1 to 40 carbon atoms; R 2 and R 2 ′ may be the same or different and each represents hydrogen or an organic group having 1 to 40 carbon atoms; R 3 is a bulky organic group having at least 3 carbon atoms, is bonded to an oxygen atom via a non-aromatic carbon atom or silicon atom, and is a halogen atom or 1 to 20 carbon atoms May be substituted with another organic group and may further contain a heteroatom selected from Si, N, P, O and S; T and T ′ may be the same or different, each having 1 to 40 carbon atoms and forming at least one other saturated or unsaturated ring with the cyclopentadienyl ring. Represents an organic group, a saturated or unsaturated ring has 5 to 12 ring members, and T and T ′ are Si, Ge, N, P, in a condensed ring with a cyclopentadienyl ring. As, Sb, O, S, Se or Te may be included, A represents a bridging group composed of a divalent atom or a divalent group, M 1 represents an element of Group 3, 4, 5 or 6 of the periodic table, or a lanthanide element; The groups X may be the same or different and each represents an organic or inorganic group substitutable by a cyclopentadienyl anion; x represents a natural number of 1 to 4, M 2 represents a part of an alkali metal, alkaline earth metal or magnesium monohalide, p represents 1 for a metal with a charge of +2, or 2 for a metal with a charge of +1 or part of a metal ion, LB represents an uncharged Lewis base ligand, and y is 0 Represents a natural number of ~ 6, A subsequent reaction of such a complex to react such a complex to form an ansa-metallocene represented by formula (IV), to produce the metallocene, formula (III) Of transition metal compounds of formula (III), transition metal compounds of formula (III), ansa-metallocene complexes of formula (I), and metallocene complexes of formula (I) as constituents of catalyst compositions for the polymerization of olefins How to use.
