专利号:US-2010113664-A1 优先权日:2008-06-11 标 题 :Asymmetric Cyclic Diester Compounds 发明人:BRADSHAW JOHN D; SCHAEFER GEORGE F; BALDWIN LARRY J; RALEIGH JR RONALD J; HOLLO BRENDA 权利人:FERRO CORP 摘要:Compounds useful as plasticizers and the synthesis thereof are disclosed. In general, the invention includes mixed alkyl/aryl asymmetric cyclic diesters where the aryl and alkyl ester moieties are attached to a cyclic structure at vicinal carbons. The invention also includes synthetic processes of making such compounds. Blends of these asymmetric cyclic diesters with other plasticizers are demonstrated to be of use in plasticizing polymers.

参考标题:Copper-Catalyzed Domino Annulation Approaches To The Synthesis Of Benzoxazoles Under Microwave-Accelerated And Conventional Thermal Conditions 作者:Russell D. Viirre,Ghotas Evindar,Robert A. Batey |发布日期:2008.5.1 摘要:Two Domino Annulation Approaches For Benzoxazole Synthesis Have Been Developed. In The First Approach, Copper-Catalyzed Intermolecular Cross-Coupling Of 1,2-Dihaloarenes With Primary Amides Initially Forms The Ar−n Bond Of The Benzoxazole Ring, Followed By Copper-Catalyzed Intramolecular Cyclization To Form The Ar−o Bond. Benzoxazoles Were Formed In Good Yields For The Reaction Of 1,2-Dibromobenzene
