R.sup.1 =R.sup.2 =R.sup.3 =R.sup.6 =R.sup.7 =H, or2. R.sup.1 =R.sup.2 =R.sup.3 =H and R.sup.6 or R.sup.7 =CH.sub.3, or3. R.sup.2 =CH.sub.3 and R.sup.3 =R.sup.6 =R.sup.7 =H, or4.

    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.

    Abstract: The present invention relates to a photoreactive polymer that comprises a multi-cyclic compound in a main chain, and a polymerization method thereof. Since the photoreactive polymer according to the present invention comprises a multi-cyclic compound having a high glass transition temperature as a main chain, the thermal stability is excellent, and since the mobility of the main chain is relatively high as compared to that of an additional polymer, a photoreactive group can be freely moved in the main chain of the polymer. Accordingly, it is possible to overcome a slow photoreactive rate that is considered a disadvantage of a polymer material used to prepare an alignment film for known liquid crystal display devices.
