| titleOfInvention | Racemo selective production of ansa-metallocene complexes |
| abstract | Formula (II): [Chemical 1] A ligand starting compound represented by formula (III): [Chemical 2] Comprising a step of reacting with a transition metal compound represented by formula (I): [Chemical 3] In the above formulas (I), (II), and (III), R 1 and R 1 ′ may be the same or different from each other. 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; 3 represents an organic group having 1 to 40 carbon atoms, R 4 represents hydrogen or an organic group having 1 to 40 carbon atoms, and T and T ′ may be the same or different, Represents a divalent organic group having from 1 to 40 carbon atoms and forming with the cyclopentadienyl ring at least one other saturated or unsaturated, substituted or unsubstituted ring. The saturated ring has 5 to 12 atom members, and T and T ′ are cyclopentadienyl. The ring condensed with may contain Si, Ge, N, P, As, Sb, O, S, Se, or Te, and A is a bridge composed of a divalent atom or a divalent group. Represents a group, M 1 represents an element of Group 3, 4, 5 or 6 of the periodic table, or a lanthanide element, and the groups X may be the same or different, each substituted by a cyclopentadienyl anion Represents a possible organic or inorganic group, x represents a natural number of 3 to 6, M 2 represents a part of an alkali metal, alkaline earth metal or magnesium monohalide, and p represents a +2 charge. In the case of a metal ion, it represents 1, or in the case where the charge is a +1 valent metal ion or a part of a metal ion, it represents 2, LB represents an uncharged Lewis base ligand, and y is 0-6. A method characterized by representing a natural number, a first method Another method for selectively producing an ansa-metallocene complex represented by the formula (IV) starting from the prepared ansa-metallocene complex represented by the formula (I), It relates to a method of using a transition metal compound of III) and a specific transition metal compound of formula (III).
