标题:The Retro-Hydroformylation Reaction
摘要:Abstracthydroformylation,A Reaction That Adds Carbon Monoxide And Dihydrogen Across An Unsaturated Carbon-carbon Multiple Bond,Has Been Widely Employed In The Chemical Industry Since Its Discovery In 1938. In Contrast,The Reverse Reaction,Retro‐hydroformylation,Has Seldom Been Studied. The Retro‐hydroformylation Reaction Of An Aldehyde Into An Alkene And Synthesis Gas (A Mixture Of Carbon Monoxide And Dihydrogen) In The Presence Of A Cyclopentadienyl Iridium Catalyst Is Now Reported. Aliphatic Aldehydes Were Converted Into The Corresponding Alkenes In Up To 91 % Yield With Concomitant Release Of Carbon Monoxide And Dihydrogen. Mechanistic Control Experiments Indicated That The Reaction Proceeds By Retro‐hydroformylation And Not By A Sequential Decarbonylation-dehydrogenation Or Dehydrogenation-decarbonylation Process.

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.

标题:Ring-expansion of cyclic olefins metathesis reactions with an acyclic diene

摘要:This invention relates generally to synthetic procedures that include the step of ring-opening metathesis of cyclic olefins and reaction with an acyclic diene co-reactant to produce olefin macrocycles by ring expansion, or alternatively. The ring expansion of the cyclic olefin is provided by three types of sequential olefin metathesis (ring-opening, cross, and ring-closing olefin metathesis). More particularly, the invention pertains to synthesis of olefin macrocycles via olefin metathesis reactions using a Group 8 transition metal complex as the metathesis catalyst. Macrocycles provided herein have a variety of uses in the pharmaceutical, biomedical, organic synthesis and chemical industries, such as the production of crown ethers that are useful as metal complexing species.

发明人：GRUBBS ROBERT; BIELAWSKI CHRIS; BENITEZ DIEGO
权利人:CALIFORNIA INST OF TECHN
摘要:A method for synthesizing cyclic polymers using transition metal alkylidene complexes as reaction catalysts is provided, wherein the complexes contain a cyclic group. Polymerization is carried out on the catalyst, using cyclic olefin monomers that undergo ring insertion polymerization, and no linear intermediates are generated. Following completion of polymerization, the cyclic polymer detaches from the complex via an intramolecular chain transfer reaction and the catalytic complex is regenerated. The invention also provides novel transition metal alkylidene complexes useful as catalysts in the aforementioned process, as well as novel cyclic hydrocarbons.
