Highly substituted alkyl-bridged ligand systems based of indene derivatives and transition metal compounds can be obtained in high yields by a novel process.

Method for producing alkyl-bridged ligand systems and transition metal compounds

Ligand systems containing indenyl structures, transition metal compounds of the metallocene type and catalyst systems comprising such transition metal compounds are described. The novel transition metal compounds can be used in the polymerization of olefins, in particular to give polyolefins having a low molar mass.

Transition metal compound, ligand system, catalyst system and its use for the polymerization of olefins

A novel process for preparing perhalogenated monoorganoboranes or diorganoboranes which makes it possible to obtain these compounds under conditions which can readily be implemented in the industry is described.

Method for producing mono-organoboranes or di-organoboranes

A boron-containing zwitterionic neutral transition metal compound which can advantageously be used for the polymerization of olefins is described. Here, the use of aluminoxanes, such as methylaluminoxane (MAO), as a cocatalyst can be dispensed with and a high catalyst activity and a good polymer morphology can nevertheless be achieved.
