标题 :Methods for synthesis of end-functionalized polyolefins
发明人：GUIRONNET DAMIEN S; HYATT MICHAEL G; WALSH DYLAN J
权利人:UNIV ILLINOIS
摘要:A strategy for the synthesis of semi-telechelic polyethylene through the palladium diimine-catalyzed chain transfer polymerization of ethylene using various silanes as chain transfer agents is reported. Polymer molecular weight and end-group chemical structure can be tuned by varying the chain transfer agent as well as its concentration. NMR spectroscopy confirms that the silicon of the chain transfer agent is incorporated into the polymer. The stability of the catalyst toward polar monomer enables the chain transfer polymerization of semi-telechelic poly(ethylene-methyl acrylate) copolymers.

标题:Method for preparing chiral alkyl compounds by asymmetric hydrogenation of olefins catalyzed by iron complex
发明人：LU ZHAN; LU PENG; REN XIANG
权利人:UNIV ZHEJIANG
摘要:Provided in the present invention is a method for preparing chiral alkyl compounds by the asymmetric hydrogenation reaction of iron complex catalysts catalysing olefins: using the disubstituted olefin shown in formula I as a raw material, atmospheric hydrogen as a hydrogen source, FeX2-8-OIQ complex as a catalyst, and a silane compound and acetonitrile as cocatalysts, and reacting for 12-24 hours under the action of a reducing agent to prepare the chiral alkyl compound shown in formula II. The method of the present invention has mild reaction conditions, simple operation, and high atom economy. In addition, the reaction does not require the addition of any other toxic transition metal (such as ruthenium, rhodium, and palladium), and has great practical application value in the synthesis of drugs and materials. The conversion rate of the reaction is also good, generally reaching >99%, and the enantioselectivity is also high, generally 70-99%.

标 题 :Polymerization of olefins

摘要:Disclosed herein are processes for polymerizing ethylene, acyclic olefins, and/or selected cyclic olefins, and optionally selected olefinic esters or carboxylic acids, and other monomers. The polymerizations are catalyzed by selected transition metal compounds, and sometimes other co-catalysts. Since some of the polymerizations exhibit some characteristics of living polymerizations, block copolymers can be readily made. Many of the polymers produced are often novel, particularly in regard to their microstructure, which gives some of them unusual properties. Numerous novel catalysts are disclosed, as well as some novel processes for making them. The polymers made are useful as elastomers, molding resins, in adhesives, etc. Also described herein is the synthesis of linear α-olefins by the oligomerization of ethylene using as a catalyst system a combination a nickel compound having a selected α-diimine ligand and a selected Lewis or Bronsted acid, or by contacting selected α-diimine nickel complexes with ethylene.
