    • This invention relates to metal complex compositions, their preparation and their use as catalysts to produce polymers of conjugated dienes through polymerization of conjugated diene monomers. The used metal complex compositions are transition metal compounds in combination with an activator compound, optionally with a transition metal halide compound and optionally a catalyst modifier and optionally an inorganic or organic support material. The metal complexes comprises metals of group 3 to 10 of the Periodic System of the Elements in combination with activators, and optionally transition metal halide compounds of groups 3 to 10 of the Periodic Table of the Elements including lanthanide metals and actinide metals and optionally, catalyst modifiers, especially Lewis acids and optionally an inorganic or organic support material .More in particular the invention relates metal complex compositions, their preparation and their use as catalysts to produce homopolymers of conjugated dienes, preferably, but not limited to, through polymerization of 1,3-butadiene or isoprene.

    • The present invention is directed to a method for preparing a 4,7-bis(5-halothien-2-yl)-2,1,3-benzothiadiazole, more particularly, 4,7-bis(5-bromothien-2-yl)-2,1,3-benzothiadiazole, and a precursor therefor, namely, a 4,7-bis(thien-2-yl)-2,1,3- benzothiadiazole. The precursor is prepared by contacting in the presence of a palladium catalyst and a solvent a 4,7-dihalo-2,1,3-benzothiadiazole with a thienyl group adding reagent, which can either be a 2-thienylzinc halide, a 2-thienylmagnesium halide, or a 2-thiopheneboronic acid, under such conditions as to form 4,7-bis(thien-2-yl)-2,1,3-benzothiadiazole. The precursor can then be halogenated, preferably brominated, to form the desired dibrominated product, which is a particularly suitable monomer for the preparation of a copolymer of a 9,9-disubstituted fluorene. This copolymer is useful, for example, in polymeric light emitting diode (pLED) applications.
    • 本发明涉及一种制备4,7-双(5-卤代噻吩-2-基)-2,1,3-苯并噻二唑,更特别是4,7-双(5-溴噻吩-2-基) )-2,1,3-苯并噻二唑及其前体,即4,7-双(噻吩-2-基)-2,1,3-苯并噻二唑。 通过在钯催化剂和4,7-二卤代-2,1,3-苯并噻二唑的溶剂与噻吩基加成试剂的存在下接触来制备前体,噻吩基加成试剂可以是2-噻吩基卤化物,2- 噻吩基镁卤化物或2-噻吩硼酸,在形成4,7-双(噻吩-2-基)-2,1,3-苯并噻二唑的条件下进行。 然后可以将前体卤化,优选溴化,以形成所需的二溴化产物,其是用于制备9,9-二取代芴共聚物的特别合适的单体。 该共聚物在例如聚合物发光二极管(pLED)应用中是有用的。
