权利人:BASELL POLYOLEFINE GMBH
摘要:The present invention relates to a specific process for the diastereoselective synthesis of rac-diorganosilylbis(2-methylbenzo[e]indenyl)zirconium compounds of the formula I, n nby reacting the silyl-bridged bisindenyl ligand with a dihalozirconium bis(3,5-di-tert-butylphenoxide)-base adduct to form the diorganosilylbis(2-methylbenzo[e]indenyl)zirconium bis(3,5-di-tert-butylphenoxide) and subsequently replacing the phenoxide groups by X using suitable replacement reagents to give the compound of the formula I; where the substituents X can be identical or different and are each F, Cl, Br, I or linear, cyclic or branched C 1-10 -alkyl; and the substituents R can be identical or different and are each linear, cyclic or branched C 1-10 -alkyl or C 6-10 -aryl; and also to the use of these compounds as catalysts.

标 题:Methods of making MOFs, systems for synthesizing MOFs, and methods of coating textiles with MOFs
发明人：GIRI GAURAV; HUELSENBECK LUKE
权利人:UNIV VIRGINIA PATENT FOUNDATION
摘要:A method of synthesis of metal organic frameworks (“MOFsâ€?) includes preparing a metal solution by dissolving at least one metal salt in an aqueous solution and buffering the metal solution with a base to achieve a first pH, the metal solution optionally comprising an organic co-solvent, preparing a linker solution by adding at least one organic acid linker and at least one base to an aqueous solution, and mixing the metal solution and the linker solution to produce the MOFs. The at least one organic acid linker has an ability to be protonated or deprotonated in response to a second pH, and the mixture of the metal solution and the linker solution has a third pH value, where the third pH value is greater than a highest pKa of the organic acid linker. The MOFs may be applied to a textile.

摘要:A catalyst and a method for preparing S-indoxacarb using the catalyst. The catalyst is prepared using 3-tert-butyl-5-(chloromethyl)salicylaldehyde and cyclohexanediamine as raw materials, where an original quinine catalyst such as cinchonine is replaced with the catalyst for application in the asymmetric synthesis of tert-butyl hydroperoxide and 5-chloro-2-methoxycarbonyl-1-indanone ester, greatly improving selection in the asymmetric synthesis process, with the S-enantiomer content increasing from 75% to over 98%, achieving the recycling of a high-efficiency chiral catalyst, and greatly reducing production costs. The synthesis process of the catalyst is simple and is favorable for industrialization, and lays good foundations for the production of high-quality indoxacarb.
