20140343238 | PROCESS FOR THE PREPARATION OF METALLOCENE COMPLEXES - 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 ZrCl | 11-20-2014 |
20140378694 | PROCESS FOR THE PREPARATION OF METALLOCENE COMPLEXES - A process to prepared bridged bis(indenyl)ligands, comprising the step of reacting a 2-indenylpinacolyl borane compound with a bromosubstituted compound in the presence of a Pd catalyst and a base to form the corresponding bridged bis(indenyl) ligand. The process may further comprise the step of 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. These bridged bis(indenyl)ligands may suitably be used in the preparation of metallocene complexes, such as 2,2′-bis(2-indenyl)biphenyl ZrCl | 12-25-2014 |

20090250400 | ABSORBENTS, PROCESS FOR THE PRODUCTION THEREOF AND USE THEREOF - An adsorbent for organic compounds consisting of filler granules, which contain 20 to 99.9 wt. % of fillers and a binder. The adsorbent is produced by mixing at least one binder with at least one filler and performing granulation in a mixing or granulation apparatus. The adsorbent may be used for adsorbing and/or absorbing organic and/or inorganic substances from a liquid or gaseous phase. | 10-08-2009 |
