标题:Pd(0) Or Pd(II)-Catalyzed Ring-Opening Reactions Of Benzylidene-And Alkylidenecyclopropyl Ketones And Aldehydes
摘要:Pd(0) Catalyzed Reactions Of Methylenecyclopropyl Carbonyl Compounds Afforded A Convenient Method For The Synthesis Of Conjugate (E,E)-1,3-Diene Derivatives 2 In Good To Excellent Yields. Moreover,We Also Found That Pd(II)-Catalyzed Reactions Of Methylenecyclopropyl Carbonyl Compounds With Water Gave 1,5-Diketones In Good To High Yields Via A Carbene-Palladium Intermediate. The Plausible Reaction Mechanisms Have Also Been Provided On The Basis Of Control And O-18-Labeling Experiments. (C) 2009 Elsevier Ltd. All Rights Reserved.
