Reaction of Diazonium Salts with Transition Metals. 4. Palladium(0)-Catalyzed Carboxylation of Arenediazonium Salts

Article abstract of DOI:10.1021/jo01300a020

Various arylamines were converted to arenecarboxylic acids in good yields via their diazonium tetrafluoroborates by reaction with carbon monoxide (9 kg/cm²) in the presence of a palladium(0) catalyst and sodium acetate.Evidence is presented which supports the idea that mixed anhydrides are initial products in the carboxylation.
