Abstract: Processes for polyurethane polymerization are provided. The processes use polysilyl derivatives of germanium and tin as catalysts. Polyurethanes made using the catalysts have increased gel times as compared to polyurethanes made using conventional processes.

Abstract: The present invention relates to monomeric bivalent phenoxy tin compounds, processes for making the phenoxy tin compounds, and processes for making polyurethanes using the tin compounds as polymerization catalysts.

Abstract: The present invention relates to monomeric bivalent phenoxy tin compounds, processes for making the phenoxy tin compounds, and processes for making polyurethanes using the tin compounds as polymerization catalysts.

Abstract: Divalent germanium and tin compounds are provided. The divalent germanium and tin compounds have been found to be efficient catalysts for the formation of polyurethanes. Methods for making polyurethanes using the catalysts are also provided.

Abstract: The present invention relates to a new method of cross-coupling aryl moieties comprising reacting an arylhalide with an arylboronic acid in the presence of a palladium compound and a compound comprising a di-alkylphosphine moiety.

Abstract: The present invention is generally directed to electroluminescent Ir(III) compounds, the substituted 2-phenylpyridines that are used to make the Ir(III) compounds, and devices that are made with the Ir(III) compounds.

Abstract: Novel iron and cobalt complexes of certain novel tricyclic ligands containing a “pyridine” ring and substituted with two imino groups are polymerization and/or oligomerization catalysts for olefins, especially ethylene. Depending on the exact structure of the ligand, and polymerization process conditions, products ranging from ?-olefins to high polymers may be produced. The polymers, especially polyethylenes, are useful for films and as molding resins.
