摘要:Metal imidazolate complexes are described where imidazoles ligands functionalized with bulky groups and their anionic counterpart, i.e., imidazolates are described. Compounds comprising one or more such polyalkylated imidazolate anions coordinated to a metal or more than one metal, selected from the group consisting of alkali metals, transition metals, lanthanide metals, actinide metals, main group metals, including the chalcogenides, are contemplated. Alternatively, multiple different imidazole anions, in addition to other different anions, can be coordinated to metals to make new complexes. The synthesis of novel compounds and their use to form thin metal containing films is also contemplated.

摘要:The neodymium catalyst system prepared by the technique of this invention can be used in the polymerization of isoprene monomer into synthetic polyisoprene rubber having an extremely high cis-microstructure content and high stereo regularity. This polyisoprene rubber will crystallize under strain and can be compounded into rubber formulations in a manner similar to natural rubber. This invention more specifically discloses a process for the synthesis of polyisoprene rubber which comprises polymerizing isoprene monomer in the presence of a neodymium catalyst system, wherein the neodymium catalyst system is prepared by a process that comprises (1) reacting a neodymium carboxylate with an organoaluminum compound in an organic solvent to produce neodymium-aluminum catalyst component, and (2) subsequently reacting the neodymium-aluminum catalyst component with an elemental halogen to produce the neodymium catalyst system, wherein the neodymium catalyst system is void of nickel-containing compounds.
