Title:
メタロセン錯体を調製するプロセス
Document Type and Number:
Japanese Patent JP6454548
Kind Code:
B2
Abstract:
A process comprising reacting a 2-indenylboranic acid (ester) with a bromosubstituted compound in the presence of the Pd catalyst bis(triphenylphosphin)palladium dichloride and a base to form the corresponding bridged bis(indenyl) ligand. Where the 2-indenylboranic acid (ester) is the pinacolester of 2-indenylboranic acid, the process may further comprise reacting a 2-bromo indene compound with pinacolborane in the presence of a Pd catalyst and a base to form the corresponding 2-indenylpinacolylborane compound. Bridged bis(indenyl)ligands may suitably be used in the preparation of metallocene complexes, such as 2,2′-bis(2-indenyl)biphenyl ZrCl2 and 1,2-bis (2-indenyl)benzene ZrCl2. These metallocene complexes may be used for the polymerization, optionally in the presence of a cocatalyst, of one or more α-olefins, preferably for the polymerization of ethylene.
