Synthesis of Aryldiazoacetates through Palladium(0)‐Catalyzed Deacylative Cross‐Coupling of Aryl Iodides with Acyldiazoacetates

Palladium(0)-catalyzed deacylative cross-coupling of aryl iodides and acyldiazocarbonyl compounds can be achieved at room temperature under mild reaction conditions. The coupling reaction represents a highly efficient and general method for the synthesis of aryldiazocarbonyl compounds, which have found wide and increasing applications as precursors for generating donor/acceptor-substituted metallocarbenes.
