专利号:US-9000209-B2 优先权日:2011-07-22 标题:Method of regioselective synthesis of substituted benzoates 发明人:KRAUS GEORGE A 权利人:KRAUS GEORGE A; UNIV IOWA STATE RES FOUND INC 摘要:A method of synthesis of para-substituted benzoate esters and acids is provided, wherein the para-substituted regioisomer is obtained substantially free of the meta-substituted impurity, the method comprising contacting a coumalate ester or acid and an unactivated alkene at elevated temperature in the presence of a metal oxidation catalyst and an oxidant. The metal oxidation catalyst can be palladium, such as palladium on carbon, and the oxidant can be the oxygen gas in ambient air. The reaction can be carried out without solvent or in high boiling hydrocarbon solvents such as mesitylene. When the unactivated alkene is a monosubstituted alkene, yields of at least about 50 or 60% of para-substituted ester and acid products, respectively, are obtained, substantially free of the regioisomeric meta-substituted impurity.

专利号:US-7271231-B2 优先权日:1995-01-24 标 题 :Polymerization of olefins 发明人:BROOKHART MAURICE S; JOHNSON LYNDA KAYE; KILLIAN CHRISTOPHER MOORE 权利人:DU PONT 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.
专利号:US-6011171-A 优先权日:1996-08-14 标 题 :Process for synthesis of tertiary carboxylic acids and the esters thereof 发明人:XU QIANG; SOUMA YOSHIE 权利人:JIRO HIRAISHI DIRECTOR GENERAL 摘要:The present invention provides a process for synthesizing tertiary carboxylic acids or the esters thereof having one or two more carbon atoms than the raw material has, comprising reacting in a strong acid (e.g., sulfuric acid, sulfuric acid-phosphoric acid, hydrogen fluoride, fluorosulfuric acid, boron trifluoride.water complex and trifluoromethanesulfonic acid) a raw material compound (i.e., olefin, alcohol, diene, diol or saturated hydrocarbon) with carbon monoxide in the presence of a specific metal carbonyl catalyst (i.e., platinum carbonyl catalyst, palladium carbonyl catalyst and gold dicarbonyl catalyst). The metal carbonyl catalyst is formed by reacting in a strong acid at least one specific metal compounds (e.g., platinum compound such as platinum (II, IV) oxide, platinum (II, IV) hydroxide, a platinum powder, etc.; palladium compound such as palladium (II, III, IV) oxide, palladium (II) hydroxide, palladium (II) sulfate, palladium (II) carboxylate, a palladium powder, etc.; and gold compound such as gold (I, III) oxide, gold (I, III) hydroxide, a gold powder, etc.) with carbon monoxide.
