专利号:US-9096519-B2 优先权日:2013-01-10 标 题 :Process for the synthesis of ketones from internal alkenes 发明人:MORANDI BILL; GRUBBS ROBERT H; WICKENS ZACHARY K; LERCH MICHAEL M 权利人:CALIFORNIA INST OF TECHN 摘要:The present invention is directed to methods for oxidizing internal olefins to ketones. In various embodiments, each method comprising contacting an organic substrate, having an initial internal olefin, with a mixture of (a) a biscationic palladium salt; and (b) an oxidizing agent; dissolved or dispersed in a solvent system to form a reaction mixture, said solvent system comprising at least one C 2-6 carbon nitrile and optionally at least one secondary alkyl amide, said method conducted under conditions sufficient to convert at least 50 mol % of the initial internal olefin to a ketone, said ketone positioned on a carbon of the initial internal olefin. The transformation occurs at room temperature and shows wide substrate scope. Applications to the oxidation of seed oil derivatives and a bioactive natural product are described.

The compounds are synthesized from biologically-based starting materials, are biocompatible, and are resistant to degradation by proteases and peptidases. The compounds and gels synthesized therefrom can be used in such applications as tissue engineering, drug delivery, separation of biomolecules, and stimulus-responsive advanced materials
专利号:US-9822053-B2 优先权日:2016-01-28 标题:Single step conversion of N-butyraldehyde to 2-ethylhexanal 发明人:BOPPANA Venkata Bharat; HAMPTON JR KENNETH WAYNE; LIU ZHUFANG; SUMNER JR CHARLES EDWAN; TUSTIN GERALD C; STEINMETZ GUY RALPH; STEFFEY MELISSA PAGE 权利人:EASTMAN CHEM CO 摘要:Disclosed is a method of making and using a titania supported palladium catalyst for the single step synthesis of 2-ethylhexanal from a feed of n-butyraldehyde. This titania supported palladium catalyst demonstrates high n-butyraldehyde conversion but also produces 2-ethylhexanal in an appreciable yield with maintained activity between runs. This method provides a single step synthesis of 2-ethylhexanal from n-butyraldehyde with a catalyst that can be regenerated that provides cleaner downstream separations relative to the traditional caustic route.
