标 题:Chiral porphyrins, chiral metalloporphyrins, and methods for synthesis of the same
发明人：ZHANG X PETER; CHEN YING; GAO GUANG-YAO
权利人:UNIV TENNESSEE RES FOUNDATION
摘要:Novel methods of synthesizing heteroatom-containing chiral porphyrins and chiral metalloporphyrins and the novel chiral porphyrins and chiral metalloporphyrins themselves are disclosed. Metal complexes of the chiral porphyrins are prepared in high yields and shown to be active catalysts for highly enantioselective and diastereoselective cyclopropanation, aziridination, and epoxidation of alkenes under a practical one-pot protocol.

标题:Effects of catalyst concentration and solid activator on nickel-mediated olefin/carbon dioxide coupling to acrylates
发明人：Iacono Pasquale; HLAVINKA MARK L
权利人:CHEVRON PHILLIPS CHEMICAL CO LP
摘要:This disclosure provides for routes of synthesis of acrylic acid and other α,β-unsaturated carboxylic acids and their salts, including catalytic methods. For example, there is provided a process for producing an α,β-unsaturated carboxylic acid or a salt thereof, the process comprising: (1) contacting in any order, a group 8-11 transition metal precursor, an olefin, carbon dioxide, a diluent, and a metal-treated chemically-modified solid oxide such as a sulfur oxoacid anion-modified solid oxide, a phosphorus oxoacid anion-modified solid oxide, or a halide ion-modified solid oxide, to provide a reaction mixture; and (2) applying reaction conditions to the reaction mixture suitable to produce the α,β-unsaturated carboxylic acid or the salt thereof. Methods of regenerating the metal-treated chemically-modified solid oxide are described.
