标题 :Combinatorial synthesis and analysis of metal-ligand compositions using soluble metal precursors
发明人：HALL KEITH; MURPHY VINCE; LAPOINTE ANNE M; VAN BEEK JOHANNES A M; DIAMOND GARY M
摘要:The present invention relates to a process of conducting research using combinatorial techniques wherein metal-ligand compositions are synthesized and screened for reactivity in reactions of interest, particularly metal-ligand compounds which are suitable for use as catalysts. In the process, an array of different metal-ligand compositions is prepared by delivering a dissolved, soluble metal precursor and a metal-binding ligand to each reaction vessel or well in the array, where they may optionally be combined with an activator and/or other additives. The resulting metal-ligand composition in each vessel is then screened for reactivity in a chemical reaction of interest, particularly for catalytic activity in a polymerization reaction.

标 题 :Ethylene trimerization using a supported chromium-tantalum catalyst
发明人：QIU HE; ZHOU BING
权利人:HEADWATERS TECH INNOVATION LLC
摘要:Bimetallic, supported catalysts for production of 1-hexene from ethylene are manufactured by impregnating a porous, solid support material with at least one catalytic chromium compound and at least one catalytic tantalum compound. The bimetallic, supported catalysts have high catalytic turnover, high selectivity for 1-hexene production, a low tendency for metals to leach from the catalysts during manufacturing and use compared to catalysts manufactured using known techniques. Moreover, the catalysts can be reused in multiple synthesis runs. High turnover, high selectivity, and reusability improve yields and reduce the costs associated with producing 1-hexene from ethylene, while the absence of metal leaching reduces the potential environmental impacts of using toxic metal catalysts (e.g., chromium).

摘要:The present invention provides Group 5 metal complexes useful for amine functionalization and synthetic process for manufacture thereof. Provided in this application are halo group 5 metal-amidate complexes having the structure of Formula I: I wherein: M is a group 5 metal, such as Ta, Nb or V; X is a halo substituent, such as CI, F, I or Br; n = 1 or 2,; s = 1 or 2; R 1 and R 2 are each independently H; a C 1 - C 25 substituted or unsubstituted, linear, branched or cyclic alkyl; or substituted or unsubstituted aryl or heterocyclic groups; R' is independently a C 1 - C 25 substituted or unsubstituted, linear, branched or cyclic alkyl; a substituted or unsubstituted aryl; a substituted or unsubstituted heterocyclic group; or NR 3 n 2 ; and each R 3 is independently a C 1 - C 25 substituted or unsubstituted, linear, branched or cyclic alkyl; a substituted or unsubstituted aryl; or substituted or unsubstituted heterocyclic group, and a process for synthesis thereof. Also provided are the corresponding metallaaziridine complexes. The metal complex of Formula I, and the corresponding metallaaziridine complex are useful as a catalysts in ct-alkylation of secondary amines and, therefore, also provided are methods of using the metal complex of Formula I, and the corresponding metallaaziridine complex in o-alkylation of secondary amines. This application also provides methods of using the corresponding non-halo group 5 metal-amidate complexes and metallaaziridine complexes in α-alkylation of heterocycles.
