[DE] Die vorliegende Erfindung betrifft metallorganische Verbindungen von Übergangsmetallen mit einem in 2-Position gebundenen und in 1,3-Position substituierten Indenyl-Liganden, ein Verfahren zu ihrer Herstellung und ihre Verwendung als Katalysatoren zur (Co)Polymerisation von olefinischen und/oder diolefinischen Monomeren.
[EN] Organometallic compounds of group 4, 5 or 6 transition metals with 1,3-di-substituted 2-indenyl as ligand are new. New organometallic compounds of transition metals with 1,3-di-substituted 2-indenyl as ligand are of formula (I). A = benzo or tetrahydrocyclohexyl system; Q<1>, Q<2>, Q<3> = hydrogen (H) or substituents in the 1-, 3- and 4,5,6,7-positions respectively; M<1> = group 4, 5 or 6 transition metal; X = anion; n = 0-4; m = 0-4; Y = -C(R<1>)(R<2>)-, -Si(R<1>)(R<2>)-, -Ge(R<1>)(R<2>)-, -C(R<1>)(R<2>)-C(R<3>)(R<4>)-, -C(R<1>)(R<2>)-Si(R<3>)(R<4>)- or -Si(R<1>)(R<2>)-Si(R<3>)(R<4>)- bridge; Z = second ligand. The full definitions are given in the DEFINITIONS (Full Definitions) Field. Independent claims are also included for: (1) new intermediate 1,3-di-substituted 2-( omega -halo)-alkyl-, -silyl, -germanyl- and -silylalkyl-indenes (II); (2) preparation of (II) by reacting 1,3-di-substituted 2-haloindenes (III) with a group 1, 2 or 12 metal or compound and a Y dihalide; (3) preparation of (I) by preparing and optionally isolating (II), reacting with a Z derivative and then reacting with a compound of transition metal M<1>. |
