Palladium‐Catalyzed Catellani ortho‐Acylation Reaction: An Efficient and Regiospecific Synthesis of Diaryl Ketones
Authors:Yunze Huang  Rui Zhu  Kun Zhao  Zhenhua Gu
Abstract:A palladium‐catalyzed, norbornene‐mediated Catellani ortho‐acylation reaction was developed by the use of either acyl chlorides or acid anhydrides as acylation reagents. The addition of more than a stoichiometric amount of H2O is crucial for this transformation when acid chlorides are used, and kinetic studies indicate that the active acylation reagent is possibly an acid anhydride.
Keywords:Acylierungen  Arene  Kreuzkupplungen  Palladium  Reaktionsmechanismen
